Note: These solutions work in all versions of IE and Outlook.

A very common question comes up often in the Microsoft forums:

When clicking on a hyperlink in an e-mail, I get this Message : “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.” I get this message every time that I attempt to use the hyperlink. I am the administrator on this stand alone computer. How do I deactivate this feature so that I activate hyperlinks ?

Restrictions in effect error in Outlook

If you use Outlook 2013, you’ll receive following error message instead of the “restrictions in effect error” message.

error message caused by uninstall firefox or chrome

This is not “an Outlook error”.

The typical cause is an application installs Chrome (and makes it the default browser) along with their own updates. When Chrome is uninstalled without setting Internet Explorer as default first, this error results. Lately, the blame falls squarely on Adobe Flash updates that install Chrome unless you opt out. It’s easy to miss the option before hitting Next.

If you uninstalled Chrome (or Firefox) and then received the error, see Edit Registry, Part 2. Thanks to Adobe Flash and other application updates installing Chrome by default, this is by far the most common cause.

In addition to Chrome and Firefox, Maxthon and other HTML rendering and editing programs may take the HTML open command and cause this error. Greg reports UltraEdit is one such program. See Edit Registry, Part 2 for the fix.

If you don’t want to edit the registry (or use my reg file), Alan suggests reinstalling Chrome (or the offending program). Set IE as default before uninstalling Chrome.

You can find solutions suggested by others users below.

If you are using Outlook 2010 or 2013, see tgrf’s suggestion to change your Junk email settings. It’s quick to try and won’t be a waste time if it doesn’t fix your problem.

If the problem is not due to uninstalling Chrome or Firefox, it could be a corrupt registry key in Internet Explorer. The registry key found at


To fix it, try resetting Web settings in Internet Explorer. If this does not resolve the issue, set IE as the default browser following the steps in Set Program Access in Control Panel. If you use a different browser as your default, you need to set IE as the default until you verify the links work in Outlook.

Edit Registry, Part 2

If you received this error after uninstalling any application that takes over the HTML open command (including, but not limited to, Chrome & Firefox browsers) you may also need to change the HTM/HTML association in the registry.

  1. Start, click Run, type Regedit in the Open box, and then click OK.
  2. Browse to HKEY_CURRENT_USER\Software\Classes\.html
  3. Right click the value for the .html key and select Modify…
  4. Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
  5. Repeat for .htm, shtml, .xht, .xhtml, .xhtm keys

Repeat these steps for htm and .shtml keys if they exist. You may also want to check the xhtml and xhtm keys. Don’t want to edit the registry? Download this file (right click and choose Save target as…) Then double click on the file to run and restart Windows.

You need to restart Windows for the change to take effect.

Reset Web Settings

If Edit Registry, Part 2 doesn’t fix your problem, try resetting the web settings.

To Reset Web settings in Windows XP:

  1. Close Outlook
  2. Open Internet Explorer.
  3. On the Tools menu, click Internet Options.
  4. Click the Advanced tab, and then click the Reset button.
  5. Under Internet programs, verify that the correct e-mail program is selected.
  6. Click to select the Internet Explorer should check to see whether it is the default browser check box.
  7. Click Apply, and then click OK.

If you receive a message when Internet Explorer starts telling you that IE is not currently your default browser, click Yes to make it your default.

If you are using Windows 7 or Vista:

  1. Close Outlook
  2. Open Internet Explorer.
  3. On the Tools menu, click Internet Options.
  4. Click the Advanced tab, and then click the Reset button.
  5. On the Programs tab, under Internet programs, click Set Programs, then “Set your Default Programs”, select your e-mail program and click “Set this program as Default”. Repeat for Internet Explorer.
  6. Click OK and close the dialogs.

Note: You need to set Internet Explorer as default and verify the problem is fixed. If you prefer a different browser, you can set it as default later.

Import a Registry Key

When resetting the web settings doesn’t help, you’ll need to recreate the corrupt key. The easiest way to do this is by exporting the key from another computer. To save exporting it from another computer, download this registry key exported from my computer. Right click on the link and choose Save target as then double click on it to run it.

If you prefer to use a key from a computer you have access to, follow these instructions to export the registry key:

  1. Press Windows key + R to open the Run command
  2. In the Open box, type regedit, and then click OK.
  3. Browse to the following registry key:
  4. On the File menu select Export.
  5. Type in a filename and Save.
  6. Close the Registry Editor.

Copy the *.reg file to the other computer and double-click on the .reg file. Ok the dialogs to update the registry.

These instructions are the same as found in the Microsoft article Hyperlinks are not working in Outlook (MSKB 310049).

You need to restart Windows for the change to take effect.

Set Program Access in Control Panel

Windows XP and Vista allow you to control program defaults through Control Panel. If the above methods fail, use this method to set the default browser. In Windows XP, go to Add and Remove Programs, Set Program Access and Defaults. In “Choose a default web browser”, check on the “Internet Explorer” option and click the OK button. In Vista, access the Default Programs applet from the Start menu or Control panel. Click on the “Set program access and computer defaults” (last option) then expand Custom. In “Choose a default web browser”, check on the “Internet Explorer” option and click the OK button.

Users Solutions

tgrf makes this suggestion as one possible cause and solution:

I am using Outlook in Office 2010, Windows 7, and IE8. I just fixed this problem when trying to set up my junk mail filter. Click on any email header. Select Junk mail menu, then Junk mail options. Clear the check mark at Disable links and other functionality in phishing messages.

Junk Filter menu

I can’t vouch for this solution (as I haven’t experienced the restrictions error with Outlook 2010) but its painless and easy to try. Links are disabled by default for all users. The restrictions error is typically caused by browser settings.

Alan’s Solution

Alan has this suggestion:

I found that re-installing Google Chrome or FireFox and setting it as the default, the hyperlinks worked. I then went to Internet Explorer and set it as the default browser. I again checked the hyperlinks, and again they worked. I then un-installed Google Chrome and have had no problems since. Hopefully this will work for others as well.

While I haven’t tested Alan’s solution, it’s logical that it will work. Possibly the most common cause is because users uninstall Firefox or Chrome while either is set as default and setting IE as default before uninstalling would prevent the problem. If Alan’s solution doesn’t work, make sure Chrome is not running when you set IE as the default browser.

From Greg Chapman: “This is IMPORTANT – Close Chrome and make sure it isn’t running in Task Manager because even when you close it, it can remain running. Open IE and reset it as default.”

Other Causes

There are several other causes of this error. In most cases, they do not affect hyperlinks in Outlook. If you found this page searching for the error message, check out the following pages. Note that if you receive this error on a computer at work, you should contact your administrator, they may want access to applications restricted for security reasons.

Empty Securetemp

This solution suggested by Lain should not cause the restriction error message, however, it’s not harmful (and can be beneficial for other reasons) so I’m going to include it here. If it works, it doesn’t have to make sense to me and if it doesn’t work, you cleaned some old files off your hard drive. It’s a win-win either way.

DELETE everything in the outlooksecuretempfolder
C:\Documents and Settings\USER ID\Local Settings\Temporary Internet Files\OLK###
now all working :o)

This path is for Outlook 2003 under on Windows 7/8 & Vista. See Outlook SecureTemp Files Folder for more information and steps needed to find the folder.

    Thanks for this!

    I have just uninstalled Chrome & Firefox, I then got the error message when clicking on e-mail links. I have followed your instructions on the "htmlfile" Regedit - and it worked...

    Thank you so much... : )

  2. Rae says

    I have been trying and I mean TRYING to get this issue fixed for about a month since I became aware of it. I wasted time with Microsoft and was treated like crap by them, they claim they tried ever possible deal to fix this issue however not one of them worked. I gave edit register 2 a try but this did not work, then I read down further and gave Alan (User soulution) a try and all I can say is Alan THANK YOU SO MUCH!!! You should work for Microsoft for these stupid problems that can so easily be solved! I wish that I had read this link earlier because I am so so so pleased to see that I now can use ALL of my Microsoft Office without any problems or issues what so ever!

  3. george says

    For me, it did not work, but it got me close. After regedit, I already had .html .... But I following the next suggestion and went to Access and Default settings. It was set to CUSTOM. (Both FireFex and Chrome had previously been removed. I changed it back to MICROSOFT, and everything if fine. Thank you for the original post and suggestions.

  4. Mike says

    Many thanks! When I saw the note about Google Chrome being previously installed and uninstalled, I was confident I had the right fix. My daughter installed Chrome, which I subsequently removed, and it was some time after that I started noticing this error cropping up. The simple fix of the registry took care of it.

  5. Sian Wiseman says

    Brilliant! Have been going around in circles for ages. I have never put Google chrome on my computer but when I sorted the Regedit as above it was there in the files. Anyway I followed the very clear instructions and it has WORKED. Thank you very much

    After applying Alan's solution - re-installing FireFox and setting it as the default, - the hyperlinks work. I then went to Internet Explorer and set it as the default browser. I again checked the hyperlinks, and again they worked.

    Excellent!! The Edit Registry Pt 2 worked a charm for Outlook 2007 on an XP machine, where I had previously uninstalled Chrome.

  11. SamF says

    I get that message. none of the above fixes works for me. I can't access Control Panel--get the same message. Can't restore--same message. It does not seem to be an IE problem as I have the same message when not online. I really need help here. I've looked all over Microsoft, various help sites and none seem to be the same problem. I can only go online, write text documents; I lost everything in "All Programs" and most of my desktop icons went away (thought I found the solution on that one, but it only restored a few). AND I have the Microsoft EULA stuck on my desktop, can't click it closed. HELP PLEASE!

    Thanks in advance

  12. elizabeth says

    i used the reset websettings.....after a couple of tries, it worked. I had to have my outlook closed when i performed the process. It did not work when it was opened.

    thank goodness for forums such as this!

  13. Valerie says

    Tried all suggestions above, didn't currently have Google Chrome (had uninstalled it in the past because I heard it was a memory hog) and when I performed the regedit....sure enough...there was Google Chrome hiding in the registry.

  23. Ben Scott says

    For those who want to know the nitty-gritty details: In my testing (Outlook 2003 SP3 on Win XP Pro SP3), it appears that Outlook is looking for the file association registered for ".HTML" files, and then looking for a "shell" subkey named "open", and invoking that. It has to be named "open".

    Outlook will chase the .HTML handler properly, using the default value for "HKCR.html" -- mine is "htmlfile_custom". However, it appears Outlook ignores the default action (the default value for "shell" -- "HKCRhtmlfile_customshell" in my case) and is hard-coded to look for a key named "open". I originally had keys named "firefox", "msie", "chrome", "safari", etc., with the default specified, per Microsoft's docs. Apparently Outlook doesn't follow Microsoft's own standards. So I had to rename "firefox" to "open" to get Outlook to work.

  24. Randy says

    I too had this problem and I found this page by Googling the error message. Modifying the reg solved this, thank you very much!!!

  25. Bruce says

  28. Michael says

    Alan, I just wanted to send a zillion thanks for your super-simple solution to this problem. The steps were easy to follow and I didn't have to retry to get it resolved. In my case Maxthon was the issue even though it was never my default browser. A quick fix in the Registry and all is well. Thanks again.

  29. dave jackson says

    thanks for your assistance with the outlook disbled hyper links. it was chrome which had prefixed the html files etc and was stopping them from working.


    i downloaded the reg file key you offered and it work a treat thanks again, have to admit was sceptical about using the file but worked well.


  30. Malcolm says

    Thanks for the advice. How dare Google go stomping all over the registry leaving chrome marks everywhere. Methinks Google is more of an evil empire than Microsoft.

  31. Susan Clark says

    I tried all the I.E. and Outlook solutions and none worked, I they uninstalled Google Chrome and reinstalled it, and voila! The hyperlinks work on Outlook and use I.E. So while I do not have to use "Chrome", I must have it installed as "default" to use the Outlink hyperlinks. Much simplier than all the other solutions I tried.

  32. Sam says


    I bet this is part of the new internet bill that Congress is trying to pass.

    And Microsoft is denying that the last upgrade to everyone's computer did something to cause this problem

    they're not going to fix it. all hyperlinks are to be cut based on the two bills going through Congress.

    I'm trying to emilinate microsoft off my computer and use other programs. maybe that will fix the problem, nothing else is working (i have tried the IE tools, the control panel solution, changing to firefox, nothing works)

    • Diane Poremsky says

      Did you try rebooting? The changes don't take effect for some users until they reboot. Use the fix in Import the Registry Key section and either use my key or the FixIt in the other link in that section (it's to a Microsoft KB) then reboot.

  33. Gary says

    Many thanks to Slipsticks Systems. My day is clogged enough without computer snags. You corrected the error (links would not open after uninstalling Chrome - change registry keys) on the first try. Waydago!

  34. KYFAKT says

    WINDOWS 7, IE 9: Okay, here is the fix that worked for me... With Outlook closed, open IE, click on Tools, then Internet Options and select the Programs Tab. Click on the Set Programs Button and then select the fourth selection down “Set Program Access and Computer Defaults”. The Custom option was selected for some reason on my machine – click on the down arrows to the right of the Custom option to expand the setting options and then select Internet Explorer as the default web browser and Outlook as the default email client and click okay. Okay your way out of the Option windows and open Outlook – Hyperlinks should work in Outlook again!

  35. Alan Did Not Work says

    Alan's approach did not solve a Word 2010 problem which prevented at least two functions:

    Ctrl+C from the Table of Contents and Check for Updates.

    I did try the install/uninstall of Chrome, plus setting IE as default, but within its Options and Also from the Control Panel.

    What worked for me was editing the Registry as suggested. I found the following entries when I went there:

    .thm & .html were Max3.Association.HTML
    .shtml & .xhtml were FirefoxHTML

    I changed them all to htmlfile

    Good luck!

  37. Michael F says

    I too got this problem after uninstalling chrome toolbar. I have Win7 SP1 & MS Outlook 2007 SP2. The "Edit Registry, Part 2" worked flawlessly. But be sure to set a restore point before you change the settings, just in case. Also be sure to change all the keys to "htmlfile": html; htm; shtml; xhtml; xht. You should NOT have to reset IE8 or 9. Once you finish, do a cold startup so that the new registry entries can take effect.
    P.S. I did try the Microsoft Fix-It, but it just hung-up and didn't do anything.

  38. G Thomas Mortensen says

    I don't know whether the default reset in IE or the downloaded file resolved it for me.

    Chrome was resident and the problem only started after uninstalling. Chrome hasn't been installed as default for a long time.

    I took both steps before testing and the problem's gone

    Hello: Since I uninstalled internet explorer I have been unable to use the Table of Contents Links in Word 2007. Is the only way to get the ability to use the links restored to reinstall internet explorer? The links are not http:// links but rather they are links pointing to sections of the word documents themselves.

    Alan's solution worked perfectly. Use the download file instead of trying to to edit your registry. Very easy. Thanks Alan!

  43. Mary D says

    Thank you soooooo much. Changing the registry worked!!! I had to get rid of Google Chrome because it had this nefarious problem with Whitesmoke search engine hijacking it and IE also. It's probably still lurking in my computer somewhere because when I tried to download Chrome again it immediately surfaced in the second tab. I got rid of Chrome and downloaded Opera instead and still have IE. So far, I haven't seen it resurface. After uninstalling Chrome the hotlinks on my Outlook didn't work and your solution resolved it. Thanks again.

  44. Alan says

    I have Windows 7 64x and recently deleted Chrome and anything I could find to do with Google, due to their snooping policy. Links stopped working and I tried the reset, as per above, and that did not work. I then tried your "edit reg part 2" above and it worked instantly.
    Many thanks - appreciated!

    Great, simple, perfect solution following Alan's solution.
    The whole conflict started by installing Google Earth and not realizing that the chrome was also attached if not uncheched.

  52. Nick Lynn says

    The error message, "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator", arose after an unsolicited attempt by Google Chrome to install itself on my PC. The solution was to edit the registry as described above, but it has taken me some time to find these instructions. It is very disappointing that a reputable company like Google feels that it has the right to waste my time and interfere with the settings in my software. Perhaps it would like to pay for the privilage next time?

    • Diane Poremsky says

      I'm not sure its fair to blame google or this -it also happens with firefox and other applications. It's caused by uninstalling the browser that is configured as default, leaving the keys orphaned. IE or Windows should be smart enough to fix it the next time you use IE...

    I hate the way google, have taken away my privacy. What used to be helpful additions to computers are now conduits to personal information. Did I say that I hate that?
    I guess the only way to get privacy back these days is to trash my computer and go live in the woods.

    Thanks for the help - worked great for me. Think my computer crashed when it had IE open and that might have caused the problem.

    Just thought i'd mention that running the reg fix file didn't sort the problem - had to manually adjust the information in the registry.

  66. ParkerB says

    Awesome fix, I am suprised how much google has got up in my business. They are getting way out of control, bye bye google. I am even thinking of bailing on my Android since the only reason I avoid Apple is that I find them to controlling. Now, Android and google are no difference.

  67. Julia says

    Thank you thank you thank you thank you !!!
    spent hours trying to solve this until I found this forum and performed the Edit Registry, Part 2 !
    AND I'm the most useless IT user. AND I managed.

    Thank you for making me feel like an IT queen!

  68. Varun says

    Thanks a Ton !!!
    Fixed the problem and spread the message in my Company so that this problem goes Kaput once and for all.

    Thanks Again.

  69. Roberta says

    Thank you very much. I tried many other options, and by changing the registry key it worked. I had forgotten that at one time I had Google Chrome, deleted the program, but obviously not everything deleted! Was not aware registry keys stuck around.

  70. Finnie says

    Thanks for directing me to enable my hyperlinks in Microsoft Word again. Following the above instruction fixed my issues.

  71. Keith Anderson says

    Thanks for the solution. This raises Google Chrome to the level of a VIRUS in my estimation...

    • Diane Poremsky says

      Microsoft gets at least some blame for not handling repairing the registry values automatically....

  72. Rich says

    The best way to solve this problem is to install Thunderbird mail client which works properly, then uninstall user hostile software like microsoft outlook and internet explorer which are the two biggest pieces of Cra6 software on the planet.

    Wise up really, Microsoft purposely puts bugs like this in their software so the can FORCE their unusable crap on people. It's really disgusting.

    In fact you can now sign up with Gmail and never have to use word or excel again, I bought my last copy of ms word and excel in 2004.

    Just uninstall outlook it's garbage software
    Windows is a 32 bit extension and a graphical shell for a 16 bit patch to an 8 bit operating system originally coded for a 4 bit microprocessor, written by a 2 bit company that can't stand 1 bit of competition.

  73. Iain says

    Tried everything then remembered a trick
    DELETE everything in the outlooksecuretempfolder
    C:\Documents and Settings\USER ID\Local Settings\Temporary Internet Files\OLK###
    now all working :o)

    Hope this helps

    • Diane Poremsky says

      Hmm. That should not have anything to do with this error... but like a couple other user-suggested solution, if it works for people it doesn't have to be logical. :) Thanks for sharing.

  74. Cameron says

    Thank you so much for your help. I have been perplexed by this message for over a month and have tried various ways to fix it. The Edit Registry, Part 2 works. I really appreciate your quick solution!

  75. Linda Howarth says

    Thanks Alan for your fix. The previous owner of the laptop must have used Chrome or Firefox and uninstalled it, hence I had the problem with my Outlook and IE. Problem all solved now, thank goodness. I just love the internet for solving computer problems as lovely people like you guys put up solutions for us that sometime Microsoft just can't help with.

  76. mat says

    thankyou very much. changed the reg as per - perfect - 3 hours of reading useless dribble from ms- reallyhate chrome now- well dislike strongly- wishmy favorites were still the same in google lol
    you rock 5 ot of 5 stars

  77. Jim Rosenthal says

    I had been trying everything for a month. Finally, the (KYFAKT January 30, 2012 at 9:29 pm) solution worked.
    I will reprint here.


    With Outlook closed, open IE, click on Tools, then Internet Options and select the Programs Tab. Click on the Set Programs Button and then select the fourth selection down “Set Program Access and Computer Defaults”. The Custom option was selected for some reason on my machine – click on the down arrows to the right of the Custom option to expand the setting options and then select Internet Explorer as the default web browser and Outlook as the default email client and click okay.


  78. Evelyn says

    'Edit Register 2' for Hyperlinks Blocked error message WORKED GREAT. After 1 day of exhausting search. Thank you, thk you, thk you Slipsticks

  79. Carlos Bomtempo says

    The ‘Edit Register 2′ worked for me (IE9 Win7) maxthon uninstalled. THANK YOU!!!! That was driving me crazy!!!!

  80. Brian says

    Hey guys thanks a lot for the help i did a couple of these tricks and in the end my problem was resolved just want to tell you that it made my day, kick ass and have a great day

  81. Reg White says

    I had down loaded Chrome sometime in the past and decided that I no longer wanted it. I then had the same problem as above
    I have spents hours and hours searching the internet for help.
    Thanks to this page the answer was to hand.
    I must admit not remembering to have made Chrome my default browser as I only use Internet Explorer.
    Thanks again
    One additional point I also have installed Firefox as I also had problems running flash player on Internet Explorer. As a result I have kept a link to this page incase I should ever need it again

  82. John says

    I noticed this problem just one day after installing firefox. I'm running W7 on Dell PC and had the problem when I clicked on hyperlinks in Word, part of Office Home and Student 2010.

    The fix was to run Microsoft Fixit50388.

  83. Phoebe says

    THANK YOU SO MUCH!!!!!!! I've been trying to fix this FOREVER now! I even gave up for a while and just left google chrome on my computer so I wouldn't have to deal with the issue anymore. the fix that worked for me was to click the reset button on the advanced internet explorer settings. Thank you so much! I've looked a multiple websites over and over again.

  84. L L Walsh says

    Thanks for the info. I was able to solve the problems that came after uninstalling Chrome. Really appreciate the info.

  85. Mark O'Rafferty says

    Tried all the above suggestions and more from other web sites - none of them worked for me. What did work for me is as follows.

    If you do try this method which involves deleting entries in the registry, please don't hold me responsible for anything that may happen afterwards (unless you win the lottery and wish to thank me with a donation).

    At our house we have multiple accounts using one machine with Windows 7 Home Premium with Outlook 2010. My wife hasn't installed Google Chrome and has no issue with hyperlinks in her e-mails. So I put on my ATS hat and concluded that the problem is a user profile one, as the problem happened to me after I installed Google Chrome (used it before so why screw up now me thinks).

    Please note that in an attempt to resolve teh issue I un-installed Google Chrome, re-set Internet Explorer as the default browser, plus reset Internet Explorer back to defaults under IE Advanced settings, but still no joy.

    Anyway while logged on as my wife, I looked in the registry under "HKCU\Software\Classes" and found that there were no entries for the following file extensions:


    So I logged on as me in User context (yes I’m very anal), and in the registry deleted all of the file types under "HKCU\Software\Classes"
    Logged off and then back on
    Launched Outlook 2010 and hey presto hyperlinks now work.

    Please note that:
    1. I concluded that there are already entries for these file types in HKCR which also appear under "HKLM\Software\Classes". So why have more entries - seems a bit over the top to me. So to me deleting them from under "HKCU\Software\Classes" wasn't an issue
    2. I think the message that appears in Outlook is because it's getting confused with mixed messages from different parts of the registry and basically says "I give up" but uses a technical phrase that doesn't really help you.
    3. I work in IT so I have no issue with hacking around in the registry and I'm not squeamish.
    4. I prefer to find a quicker solution than play around with loading and re-loading of software (which in fact didn’t work for me). Also in my job when you have 20,000 PCs to fix you need a solution that can be rolled out and applied automatically and not have to ask the customer to uninstall and then re-install. If that happened the Help Desk would go into melt-down.

    ATS = Analytical Trouble Shooting
    HKCU = HKEY_Current_User
    HKCR = HKEY_Classes_Root
    HKLM = HKEY_Local_Machine

    • Diane Poremsky says

      I have no idea why there are two sets of Classes entries, but I do know that google is one company that writes to HKCU\Software\Classes, as does AVG and Office. If the keys are needed, the application that needs them should add them back.

  86. Lema says

    Thank you SO MUCH for such a clear, simple and easy to carry out solution to an awful and frustrating problem!!!

  87. need4steer says

    Thanks a lot for this detailed page.
    It's superb!.

    BTW I used the solution described under "Edit Registry, Part 2" and it worked perfectly.
    I also noted Microsoft via their KB article feedback system to add this solution.

  88. Tracey says

    Edit Registry, Part 2 WORKED!!!!!!!!! Thank you SO much!! No one else had a clue of how to fix it. I was having no problems until Avast told me it was "updating." It actually installed Google Chrome without my knowledge. I want no part of Google anything, so I uninstalled it and immediately could no longer open links in my e-mails. Two days of calls to my computer guy got me no where. I tried a system restore...or 5 and received an error saying it didn't restore or change anything. After an hour of searching the net, I found this article and within 5 minutes, was fixed. THANK YOU!!!

  89. Bob says

    Edit Registry, Part 2 worked for me too after I tried a couple of things suggested on other sites which didn't work. This discussion is the only one which gave a logical explanation of why it happened.

    Especially thank you to Tracey for explaining that Avast installed Chrome during the update. I couldn't figure out how I got Chrome all of a sudden when I didn't think I had done anything to install it.

  90. Dee says

    Thank you so much!

    Google Chrome force-added itself to my computer during via an avast (who is supposed to be PROTECTING my computer) update. After removing Chrome again, all my outlook links were stopped.

    regedit, navigate to the deepest hiddenest part, and changed all the ChromeHTML back to my preferred browser. I now can use my email and links happily.

  91. Nick says

    I had two users who just had IE as their default web browser. Their links in outlook stopped working.

    I installed chrome for one user, firefox for another user. In both instances, this caused the links in outlook to start functioning again - and open with IE as the default. GO FIGURE!

  92. Jan says


    Used a bit of Alan's workaround:
    Made Firefox default - then it worked.
    Then made IE default - and now it works :-)

  93. Jim Handy says

    What a great guide! I use Avast antivirus which, when I updated it, automatically installed Chrome and made it my default browser without telling me (unless I overlooked something!) When I uninstalled it I suddenly couldn't open hotlinks in my e-mail.

    Your solution set everything right PRONTO!

    I should add that my first choice was to go to the Microsoft site that Google pointed me to - what a waste of time! It basically said: "You're in the wrong forum. This is the Explorer forum and you should look in the Office forum!" Enough of that! I clicked on your link and am sooooo glad that I did!

    Many thanks!


  94. Pamela says

    Hey -- thanks, guys. Microsoft tech help website referred me to you and fixed in 5 minutes. I hate Google!

  95. prashant mukadam says

    Hi all,
    I am not able to open hyperlink in excel 2000 error message coming this operation is canceled due to restriction on this computer.please contact system administrator.and i am used internet explorer 7 and used windows xp sp3 so please urgently help me.

    • Diane Poremsky says

      Did you try any of the solutions on this page? Any of the solutions - Edit Registry solution, Alan's solution or Microsoft FixIt - should work with Excel. (The Junk mail or Outlook-specific settings won't apply to Excel.)

  96. erica says

    I just edited the registry and the problem is resolved. It looks like Chrome was the catalyst for my problem too.

    Thank you for posting this!!!!!

  97. Linda says

    After performing the registry changes and program & browser changes and even after the FIX-IT there was no change. After I tried Alan's suggestion of installing GoogleChrome, then choosing IE as the default the problem was fixed! I am now able to open links in my Outlook 2007 messages! I never would have thought of that fix.

  98. Harold says

    I have Win7, outlook 2007. It worked for me when I changed IE as default browser then back to Chrome as default.

  99. Ben Morling says

    Just had this issue myself having got a new laptop and moved from outlook 2007 to 2010. in regards to the file tree thing, I could not for the life of me find the .html extension in contacts, however I solved the problem be reinstalling google chrome (removed it from my new laptop as it's rubbish), but having read a few more comments and forums, I reinstalled chrome, kept IE as my default browser and now all my email links work again... the issue is Goggle Chrome, but as long as you have it on the system somewhere it should work fine. So if you've removed Chrome and still having issues (like I did) reinstall chrome and it should work,

  100. AnnMarie Deis says

    Not sure if this is an issue caused by installing Chrome in the first place (HUGE MISTAKE!!!), but when I tried to do "Edit Registry, Part 2," my .html key was gone. I couldn't find it at all! Does anyone have any advice on how to correct this? Google has been my nemesis!!!

    Thank you!!!
    P.S. Of course, I cannot click any links in my emails, either . . . . .

    • Diane Poremsky says

      Try the reg file I provided or the link to the FixIt at Microsoft - the key should be there but if not, either method will restore it.

  101. Barbara Middleton says

    This operation has been cancelled due to restrictions in effect on this system contact your administrator.

    This stuff does not work as I can not even begin to use Internet Tools because THAT is when it pops up..tried managing add on's and can t do that either..I am a newbie at this..I can not afford since my husband died in January/ get a pro for this..

  102. Sara says

    Thank you SOOO much for this FIX! I am very cautious about changing registry keys - but this made so much sense. Chrome was a bad download and I believe that it caused the errror when I uninstalled.

  103. Roger says

    Thanks so much for the regedit solution which worked perfectly. It's sad that Chrome uninstall doesn't uninstall correctly and they get away with it.

  104. Joyce Blodgett says

    tgrf, THANK YOU!, from the bottom of my computer's heart, thank you so much! That one simple thing cleared up the problem I've had for the last three days. You saved me an expensive home visit from my local computer repair tech, and I can access my links. I deeply appreciate your contributing this solution!

  105. Chelle says

    Alan's suggestion worked!!! I installed Google Chrome set it as default and was able to open the link in Outlook. I went back in to IE and set it as default browser and I'm running fine!
    Thanks Alan!

  106. Jeff Wilson says

    My problem is I download vGrabber from youtube and no matter what I do I can't get it off the toolbar. It acts like a virus and slowly corrupts the entire system. Any help would be appreciated.

    • Diane Poremsky says

      According to articles at Bing, you need to uninstall vgrabber (Add/Remove programs) and reboot. Others say to let your antivirus software quarantine it then empty the quarantine.

  107. Menji says

    Changing the registry did the trick. I'm on Office/Outlook 2010 on Win 7. Some downloads package Chrome with it, and if you're not looking, Chrome will do an Auto load and can screw up the registry. Thanks for this hint. Fixed the problem!

  108. Alan J. Talbert says

    I worked several hours on this problem! Alan's (not me) solution finally worked for me. Google should be stood up and shot for permitting this problem to persist.

    • Diane Poremsky says

      Microsoft gets some of the blame - when a program that is set as default is removed, the file types it 'owns' should be reset to the default. While google could do this during the uninstall, windows could make sure it happens.

  109. Spoon says

    Excellent guide! Clear, concise and easy to follow, with alternative methods for "the difficult bits".
    Tried and tested, works for me. Thank you very much!

  110. JK says

    Thanks Alan -- you are a genius. This error was very frustrating -- where to start. It could have been anything: Outlook 2003, IE9, Firefox, Kaspersky, my recently installed ATT gateway or something else.

    Little did I realize it involved an inadvertant download of Chrome (which I subsequently deleted) in a CCleaner upgrade. I forgot to uncheck a Chrome download box -- sneaky Google.

    Anyway, Alan's solution worked perfectly. I am bookmarking this site. Thanks again.

    • Diane Poremsky says

      I think we all hate the 'extra software' installations that are opt-out rather than opt-in.

  111. Tammy Van Boening says

    Forgive me for being slow, but I too had this issue after uninstalling Chrome. I am following the instructions for editing the registry. For xhtml and xhtm keys, do I set those htmlfile or xhtmlfile?

    Thanks so much,


  112. Orac60 says

    i had a problem with my hyperlinks opening and tried everything people wrote
    to no avail then i downloaded and ran cc cleaner off any site and heypresto
    it works fine now

    • Diane Poremsky says

      I don't recommend using registry cleaners - they can create a mess by "fixing" the registry by deleting or repairing keys that don't need "fixed".

  113. Jim Smith says

    Thank you so much for putting together such a clear and comprehensive solution to the e-mail link problem.

    Take care and God bless!

  114. Nelson Saraiva says

    Thank You Diane!
    The manual registry edit worked just fine for me.
    Such a nuisance but so easy to fix.

  115. Mike H. says


    Thanks so much for this information. I used to file you thoughtfully included in the "Edit Registry, Part 2" and it worked seemlessly.

  116. Sandyj says

    Thank you so much. I have learned from past experience to just Google my error msgs and get the solutions to my problems immediately. It saves so much time and consternation. That is what I did with this error msg and there you were right at the top of the heep. Bless you, you didn't take the time out in vain.

  117. David A. says

    Thank you, Diane! I imported your registry key and restarted Windows7 and my IE 8 and it worked like magic. I tried quite a few things first, such as downloading Google Chrome again and letting it sit there behind my IE 8 that I made my default browser; went through the Options again and made sure everything was okay. Nothing worked so at last resort I downloaded your registry key. In my manuscript in Word 2007, I have 46 chapters in my table of contents that have links to the Chapter headings. Every one of them, using CTRL-Click comes up with that error message "This operation has been cancelled...etc..." Further along at the end of the manuscript I have two links to my web site that didn't work, but after using your registry key, both links bring me to my web site! Thanks, thanks, thanks!

  118. enigma says

    reinstall and uninstall chrome fixed the error.
    Now when users browse on IE it is extremely slow, however when logged in as an admin it works perfectly fine. seems chrome have changed domain group policies too ?
    This is on a SBS 2008 64-bit terminal server.
    Any help would be much appreciated.

    • Diane Poremsky says

      Chrome can't change group policies. It's probably related to terminal services. I'll see what I can find out.

  119. gingerskeeper says

    Importing the Registry Key edit worked for me. Thank you for posting the solutions and making it easy to find!

  120. Ash M. says

    Thank you for this most helpful solution.

    Google Chrome came as a 'trojan' to a recent Adobe update. I really don't like that kind of sneaky marketing. I can say that I won't use Google Chrome on principal in the future. Their marketing has backfired.

  121. Henry says

    You are officially awesome! I tried a number of the quick fixes you referenced to get my hyperlinks working again in Outlook 2010 after I uninstalled Chrome but they did not work. Your regedit changes did the trick though! All this started because I opened Chrome and although it opened many times in the start task manager it would only open and stay minimized no matter what I tried so I uninstalled it and reinstalled it and that's when the Outlook hyperlink issue started. Now can you tell me how to get Chrome working right again?

    Thanks for sharing your smarts with us!

  122. yaseen says

    Thanks to ALLAH Almighty!!!!! HE is the one who guide us to the right thing....Like HE guided me this website....This Edit Registry part 2 is awesome...It really works....I closed outlook & uninstall chrome first and i double clicked on auto registry editor(i.e., found in Edit registry part 2- download file)....Explore outlook and tried open the hyperlinks....It works!!!!!

  123. Alex says

    Excellentarticle. Had I not been successful with a simple System Restore, I would have used both registry fix recommendations, as I looked in the key for Local_User and did not find a single key for .html, .htm, or the others found in the registry fix 2 file.

    Thank you so much.


  124. JD says

    Edit Registry Part 2 Worked for me! I encountered this problem after installing Google Chrome. I am running Windows 7 and Office 2010.

  125. Fred says

    THE ROOT CAUSE OF THE ENTIRE PROBLEM IS GOOGLE CHROME being bundled up with the free version of Acrobat Reader or some other common programs. ALAN'S SIMPLE METHOD FIXED IT (follow his solution called "Edit Registry #2"). I have been trying to fix this problem for days on my 2 week old Windows 7 HP computer which is running IE9 and Offfice 2010. People are so careful not to download a virus or malware and then you find out that Google sold you out by changing your Registry without your consent (Microsoft's normal uninstall procedure to immediately uninstall Chrome did not reverse these hidden Registry changes). I am not a computer person and never intended to download Chrome; so thank you Alan for detailing out the simple to follow step-by-step solution, without having to uninstall or reinstall any my favorite programs. I now know to always set a Restore Point before I do anything regardless of how harmless it might seem.

  126. Brian says

    I had Chrome and Google Toolbar installed as a drive-by with an update to Adobe Flash earlier this week. That's the first I've seen this behavior. In most cases, there is a check box to not install a product, but not this instance. In fact as it was downloading, there was no cancel key either. Chrome took over as the default browser without asking or launching. I uninstalled Chrome and the Toolbar before resetting IE9 as my default browser. After that, hper-links didn't work in Outlook 2010.

    Resetting the registry keys (Part 2) by hand so I can see what was being changed/not changed worked to restore functionality to Outlook. Thanks!

    • Diane Poremsky says

      The checkbox was there when I installed Flash on a new computer. I wonder if it stores the install options and reinstalls it if you ever installed flash with that option set? That is even sneakier than enabling the option by default. (My fingers clicked Next button faster than my brain could process the screen but I was able to cancel the dialog and restart it - with the option off.)

  127. Peter French says

    Trying to implement Edit Reg 2, I can navigate all the way to \software\classes\ but there is is no ".html" key whatsoever. What next? Very frightened to mess with Registry!!! Use W7 & IE9 & OL 2012

    • Diane Poremsky says

      i recommend downloading the reg file, open it in notepad so you can see what its going to add to the registry then double click to run it and update the registry. That way you wont have to worry about anything going wrong.

  128. Mats says

    If you install Notepad++, and set it to be the default editor for .html, this will also happen. Thankfully, Notepad++ will create a backup with the old (Default) value in HKEY_CURRENT_USER\Software\Classes\.html.

  129. TheWilksta says

    Franks regedit hack worked for me! I tried all other potential solutions but none worked... Frank, this worked like a charm!!!

  130. Judy Gurtner says

    I utilized the file under "Edit Registry, Part 2" and it work great to solve my problem. I had installed an update to Adobe Flash and it had installed "Chrome Toolbar" without my permission. I can now click on an RSS feed link in Outlook again. I will definitely keep your website as a Favorite!

  131. Larry says

    The "Edit Registry, Part 2" worked for me. Kudos for a detailed and clear explanation for resolving this problem - far superior to anything offered on the Microsoft support site.

  132. H.A. says


    1.Start, click Run, type Regedit in the Open box, and then click OK.
    2.Browse to HKEY_CURRENT_USER\Software\Classes\.html
    3.Right click the value for the .html key and select Modify…
    4.Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
    do the same for HKEY_CURRENT_USER\Software\Classes\.htm

  133. Harle says

    I deleted Chrome browser (after it auto installed with another software install, I hate that!) and ran regedit advice and it worked a treat. Thanks!

  134. Thanks ALLAN says

    Thanks, Installed Chrome as default browser> then set IE to default browser in Internet explorer program defaults.. and all good

  135. Jackie Brown says

    THANK YOU sooooooo much for Edit Registry Part 2 - it worked instantly!!! Nothing else worked until this!!!

  136. Mark says

    For me this was fixed by going into Set Your Default Programs in the Control Panel and going into Choose Defaults for IE. Once in the choose defaults, all the individual boxes were checked, but Select All was not. I chose Select all and boom...problem solved. Odd but it worked.

    It might also be worth clicking the Set This Program as Default Option to see if that works.

    • Diane Poremsky says

      After reinstalling Chrome, you need to set IE as the default browser then you can uninstall Chrome again.

  137. David Harvey says


    I'm a sysadmin at a company that received a whole order of computers with this problem out of the box. I've had the "benefit" of a lot of trial and error, and I figured I'd share my results.

    Editing the settings on "set your default Programs" seemed insufficient in our case, and the registry fix didn't work because we seemed to be missing a lot of keys. Uninstaling and reinstalling chrome also had no effect.

    A few options down from "set your default Programs" is a similarly titled but different option: "Set program access and computer defaults."

    Opening that up, going to custom, and selecting Internet Explorer seems to resolve the problem. I'm not sure why, but setting it here vs other places seems to do more.

    I took a pre/post registry snapshot in the hope that I could tell you exactly what that step does. The answer is A LOT.

    Deleted: 2 keys, 12 values
    Created: 189 keys, 274 values
    Modified: 60 values

    It's frustrating -- very frustrating -- that Chrome makes such a mess of things.

    Kind regards,

  138. Kelly says

    Worked like a charm! Thank you so much. Didn't even want to install that stupid Chrome, now I am back in business.

  139. Les says

    Alan's suggestion worked - until I uninstalled that damn Chrome again. I went through the whole process again and have now left Chrome installed. Outlook links now work perfectly once more.

    • Diane Poremsky says

      After you reinstall chrome, you need to set Internet Explorer as the default browser before uninstalling it. On the other hand, its not a big deal to leave it installed.

  140. Andrew Gumbrell says

    Thanks a lot for this solution.
    How could we make Chrome, Firefox etc clean up their mess when they are uninstalled? It's like throwing out a lodger you no longer want but they still expect to use your address and phone.

    • Diane Poremsky says

      Unfortunately, you can't. I blame windows for not doing a better job at avoid the error, like set the keys under classes when it's set as default browser.

  141. Andrew Gumbrell says

    I guess it's just one of those problems. You *could* get Chrome (et al) to restore the values, but they would be the values when Chrome etc. was installed, not the values you wanted. Life is not easy.
    I found I didn't need a reload (W7 (64) for Excel 2010)

  142. Stan says


    I had uninstalled Chrome, I then got the error message when clicking on e-mail links. I have followed your instructions on the "htmlfile" Regedit - and it worked...

    Thanks again!

  143. John says

    Thanks! My computer got abused by an Adobe update - it slammed Google Chrome onto my box without asking me, which is very unethical. When I uninstalled Google's crapware (all google software is poorly written, Chrome is a fine example - it does not even uninstall correctly and leaves a mess on your box). Shame on Adobe and Google - I'm going to avoid their products in the future!

  144. Jim says

    I had just install Win 8 Pro and reinstalled Outlook 2012. I used the Edit Registry, Part 2 solution and it worked perfect for me.

  145. Katie says


    This is what finally worked for me! Thank you so much!!!

    WINDOWS 7, IE 9: Okay, here is the fix that worked for me... With Outlook closed, open IE, click on Tools, then Internet Options and select the Programs Tab. Click on the Set Programs Button and then select the fourth selection down “Set Program Access and Computer Defaults”. The Custom option was selected for some reason on my machine – click on the down arrows to the right of the Custom option to expand the setting options and then select Internet Explorer as the default web browser and Outlook as the default email client and click okay. Okay your way out of the Option windows and open Outlook – Hyperlinks should work in Outlook again!

  146. Emily says

    Thank you so much.

    I used Edit Part Reg 2 running Win 7. Granddaughter downloaded Firefox after uninstalling problem started. Downloaded the file, ran it and back in business. So much help after much frustration.

    So simple yet so difficult!!
    Thanks again!

  147. Roger says

    I had this happen on Windows 8 after uninstalling the Torch browser (basically a Chrome clone). The Microsoft Fixit says it's not modified to run on Windows 8, and I had tried all the other steps and nothing fixed it. So I saved the Microsoft Fixit, and then ran it in compatibility mode, and that took care of it.

  148. pietro mellini says

    My feeling is that hyper-link problems can be determined by user account configuration.
    I experienced hyper-link error in MS Word 2003, and tried, without success, many solutions which were suggested around the Web.
    Then I found that the hyper-links began to work fine anew if I changed the user account
    (I found that just an account in my Windows XP SP3 PC was affected by hyper-link error).
    Perhaps this found may help some other user.

  149. Drew says

    editing the registry worked for me. can't thank you enough for the assistance! this has happened to me twice in 2 months. G** D*** Chrome!

  150. Paul Wyatt says

    Thanks for your assistance. I uninstalled Google Chrome, which had adopted the html registry keys. I then downloaded your .reg file from your link above, and imported that into my registry. This has resolved the problem.

  151. John A Turek Jr says

    Glad I found this site. Had issues with hyperlinks quit working in Outlook 2003. Seemed to happen right after I ran System File Checker Tool for Win-7 to correct another issue. Those were fixed, then this happened.
    Tried all the manual settings thing, but nothing. Did not want to dig into the registry, so I tried this: MS-KB310049, and ran MS Fixit # 50388.
    Saved Fixit to Downloads file, colsed everything, then ran it. Ignored Target, clicked Next to all tabs, and it did its job very well.
    Give it a try; fast and easy, and all I had to do was reopen IE9 and reset some web site's passwords.

  152. Luis Rafael Cosme says

    Of course mine has to be the strangest of issues. I just uninstalled a program from my computer and restarted and I get this error on everything. I'm on Windows Vista, Dell inspiron laptop.

    Mine has nothing to do with microsoft or links. I cannot access anything on my computer any more, meaning, the control panel is gone. Also when I right click on top of "My Computer" and click on properties I get the error.
    If I try to change my desktop wallpaper I get the same error. I cannot go into revert my computer to an earlier date because the system restore is also restricted! :-)

    • Diane Poremsky says

      Wow. What program did you uninstall? The symptoms sounds sorta like the scareware virus scam where it tells you the computer is infected or the drive is failing and try to make you buy their junk. Reboot in Safe mode (I think you press F8 key to bring up the boot options) and run system restore from the command line.

      boot in safe mode with command line and type this in when the c: prompt comes up:

  153. Luis Rafael Cosme says

    I'm almost pretty sure it's not a virus because I keep this one computer completely off the network. The program that I un-installed was Pro Tools 8. I'll give your suggestion a try now and repost. Thank you so much Diane!

    • Diane Poremsky says

      That's an audio/visual program? I don't see how uninstalling it could screw everything up, but who knows... hopefully safe mode will get you back in business.

  154. Luis Rafael Cosme says

    Yes, Pro Tools is a professional audio recording/editing program from Avid. I've been using this program since 2002 and during changes, uninstalls, and upgrades I have never ran into something like this, but there's always a first time :-)

  155. Luis Rafael Cosme says

    Sorry, I got it. It finally came up and I selected a restore point. It also showed that the last drivers package that I installed a few days ago was for Quicktime and iTunes. I chose a date before that. It's doing it now. I'm keeping my fingers crossed!

  156. Ilene Glatfelter says

    Awesome! I followed your information and it fixed our computer! I am not techy and was able to follow your links to get this corrected. Thank you!

  157. Luis Rafael Cosme says

    I'm back in business! The control panel is back in the start menu, and I can right click on my computer now to access properties again. That was definitely a moment! :-) Thank you!!!

  158. Annie D says

    Hi - many thanks to Alan - who recommended installing Google Chrome! the hyperlinks in my Outlook emails worked after I installed this programd, AND I was able to re-set the default web browser to IE as well.


  159. Michelle Zebell says

    THANK YOU THANK YOU. I was waiting for my company's tech support guy to call me back to help and I fixed it myself through this site!

  160. Wulf says

    I used a registry cleaner and after that I was receiving this error. I was attempting to do the manual edit but imagine my surprise when I find there is NO .html entry in my registry. Will see about reloading one of the browsers as specified here to fix the problem.

  161. Wil says

    Thank you!! After reading all the fixes I remembered I'd uninstalled Firefox a few months ago. I'm using Windows Mail in Vista and clicking on a link in an email worked fine. The error message popped up when I tried clicking on a link in a .doc or docx document from MS Office Word 2007. I followed the instructions under "Edit Registry, Part 2" Actually I did the "save as target" shortcut method. It worked slick as a whistle. Thanks again!

  162. JEP says

    Thank You All.
    I installed Firefox a few months ago. The error message came up when I tried clicking on a link in a .doc or .docx document from MS Office Word 2010. I followed the instructions under
    - "Edit Registry, Part 2"- so I download the file and save it (I just followed the "save as target"), and It fixed my problem.

  163. CP says

    We tried all the methods above and Alan's method worked. It logically made sense. We have Win7 64 bit running Outlook 2010 and IE9. We installed Chrome; set as default and reset IE as default. This all started after a Windoze update was installed. Thanks everyone for your efforts, solutions and feedback.

  164. Judy says

    Thanks for the tips. I was reminded that i had recently uninstalled Chrome and was easily able to edit the registry from the instructions given.

  165. bob says

    Thank you for your help, the PC I had problems on had Chrome originally installed and I had to remove it, not suspecting this problem. Running regedit was the fix for me for my Win7 PC. I had to run for all users, FYI.

  166. Shirley says

    I have windows 7 - tried everything and nothing worked until I tried Alan's suggestion of installing Chrome back - changing the default back to Internet Explorer and then uninstalling Chrome - Thank you Alan

  167. Robert Youngberg says

    Under Edit Register Part 2 - You may also want to check/change .xht in addition to the .xhtml and .xhtm keys. The real question why doesn't Google with all their billions of $ produce reliable software? I ran $20 Miilion software development projects for Oracle and Sun Microsystems and would never let this happen! And how did Chrome get installed in the first place? I can ony guess it was installed when automatically updating some other software. SHAME Google! SHAME SHAME SHAME!!!

    • Diane Poremsky says

      As much as i dislike google, they can't take all the blame, although they could alleviate a lot of the problem by requiring companies who offer to install chrome make it 'opt in', not 'opt out'. Of course then no one would install Chrome when they install other software or updates. Adobe Flash gets most of the blame and this error spikes when a new flash update is installed.

  168. LC says

    I used Allan's solution and it worked. I accidently installed Google Chrome today then did uninstall. This must have caused the problem, however after deleting Firefox and reinstalling,then making IE my default browser all is well. Thanks Allan.
    Google Chrome does nothing for me !

  169. Bill says

    This happened when I uninstalled Google Chrome, which came in with a software load. I reinstalled Google Chrome, closed my browser and reopened which gave me the choice to set IE as my browser. Then, I opened my MS Outlook 2003 and all the links on the messages worked perfect. This is a very uncomplicated fix that works easily for us computer challanged who are terriried of playing in the system registry-HA. Thank you for your site-Bill

  170. james says

    I did not want Chrome in the first place and when I deleted it, the problem occurred. Changing the htm links in the registry to htmlfile worked. Thanks.

  171. Jack says

    My goodness SlipStick. Thank you so much for this clear and detailed explanation. The registry part 2 fix worked well for me. It was simple to implement.

  172. david wyskiel says

    THANK YOU!!!!!!!!!!!!!! This has been a thorn in my side...I tried Microsoft's solution twice. Problem was exactly as james said above: I never wanted Chrome in the first place.

    Five stars for your solution - where do I send the customer support check? ;)


  173. Chad says

    Great article. Thank you. I had the registry key issues after uninstalling Chrome (which I was forced to install after upgrading Adobe Flash). Worked like a charm.

  174. Jerry says

    Changing the reg/ worked. But if you do a reg/search for chromeHTML it shows up in several other locations. Should these also be changed or just dump them? Win/7 IE9 - Reg/ had a diffrent **HTML than what was in the suggestion but change it anyway to htmlfile and IE9 will outlook links will work again. Thanks great an help full info.

    • Diane Poremsky says

      I would probably leave them if everything seems to be working OK.... html, htm, xhtm, xhtml, shtml are the problem keys.

  175. Jim (leptonjim) says

    Thanks. In my case it was the google chrome debris that caused my problem. Changing the regisrty entry back to htmlfile worked.

  176. Marcis Esmits says

    Thanks for the good info. It solved my IE and e-mail issues.

    However, I first noticed the "this operation has been cancelled...etc." message when I clicked on a heading in a Table of Contents in Word (CTRL + click).

    I made all the changes suggested but the ToC issue is still there. Am I the only one who has encountered this problem?

    If someone has solved this, please advise.


  177. word1 says

    thank you, thank you, thank you - Goggle Chrome should be stood up against a wall and shot with a ball of it's own sh*t.
    I downloaded and installed it by mistake and against my wishes, with Adobe update.
    And it did not clear the registrar after I deleted it with the control panel. I am ruining win7 - 64 bit.
    Once again, thank you, thank you, thank you. . .

    • Diane Poremsky says

      Adobe needs shot for installing it by default... Google needs to stop paying for every install that gets dumped on unsuspecting users.

  178. Dan in CT says

    Alan's solution worked immediately with Firefox. It didn't work with Chrome because, unless you already have it on your system, it hits the same "system administrator" block.

    Thanks very much. This resolved a month-long problem.

  179. Michael Klima says

    Very good explanation, Solved my problem with Win7 SP1 and MS Outlook2010, MS Excel 2010. Unfortunately I reset IE to default values.... Would be interesting to know if your hints (deleting ChromeHTML) would have worked without all other attempts. (btw: I deleted ChromeHTLM in html; htm; shtml; xhtml; xht)

  180. Arthur says

    Brilliant-Edit Registry Part 2 worked for me too.I think Chrome(accidently installed with Flash Player!) should carry a Government Health Warning!

  181. Susan says

    MY LOVE--Sending All my love & thanks for the Regedit CURE for the SOOO annoying operation cancelled prob in Outlook--I wish I would have checked here first--who knows what settings and macros and trust centers I have improperly changed!!! Thanks sooo much for the CURE!

  182. jeremy says

    You might have mentioned this already but I didn't see it.

    I fixed this issue by setting the association of the .url file type with internet explorer. It's also under Default Programs->Associate a file type or protocol with a specific program. Well for Vista at least.
    When Chrome gets uninstalled when it's set as the default browser, the association for url defaults to "Internet Browser" as if you don't have one installed. For whatever reason restoring all of IE's defaults resets everything BUT the url association.
    I'm sure the registry fix is a better solution but this worked too.

  183. Pauline says

    Thank you. Thank You. THANK YOU! "Alan's suggestion" worked for me. Win 7, Outlook 2010, IE 9. And fie on Adobe for sneaking that in without asking for permission. I thought they could be trusted!

  184. JDeesten says

    THANK YOU!!! After spending several hours trying different options I found your solution. I downloaded your file, ran your program & restarted my computer...and it took me only about 3 minutes. I did not intentionally load Google Chrome, it came in an Adobe Reader or Adoble Flash update...not sure which one. Immediately uninstalled and then started having problems. Bless you for taking the time to educate us more technically challenged people!

  185. d.attomic says

    What a genius! Thank you! Google Chrome has caused more problems for me than it was worth (it may have ever corrupted other user accounts on this computer which prevented me from logging into them ever again). Fixing the registry was that only way that I was able to get the hyperlinks to work again - no other fixes worked. When I went into the registry I knew this fix was going to work immediately because I saw that the values in all the files were set at ChromeHTML even though I had uninstalled Chrome from my computer. Thanks for this fix:
    1.Start, click Run, type Regedit in the Open box, and then click OK.
    2.Browse to HKEY_CURRENT_USER\Software\Classes\.html
    3.Right click the value for the .html key and select Modify…
    4.Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
    5.Repeat for .htm, shtml, .xht, .xhtml, .xhtm keys

  186. ledieb says

    I installed the Win8 Start Button from Torch Media, so that my Windows 8 would have the classic Windows 7 Start Menu. I was then unable to open any hyperlinks directly from my Outlook email. I get the error message “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.” I found this site and followed the instructions:

    Start, click Run, type Regedit in the Open box, and then click OK.
    Browse to HKEY_CURRENT_USER\Software\Classes\.html
    Right click the value for the .html key and select Modify…
    Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
    Repeat for .htm, shtml, .xht, .xhtml, .xhtm keys

    I noticed that the values for all the keys were set to TorchHTML.Changing the values to "htmlfile" fixed the problem. I am sharing this in case anyone else has the same problem.

  187. Jim says

    After 3 hours on with Microsoft fFxit to no avail I tried re-installing chrome and re-started my computer. Guess what, after months of working on this darned thing,,, I can now click on a hyperlink. Many, Many thanks.
    Jim Walker

  188. says

    don't forget to close Outlook or whatever program is giving you the message and restart before testin

  189. chbob says

    Rather than mess with the Registry, I did the following that fixed the same problem in Outlook 2003 and Outlook 2010.

    I reinstalled Chrome, allowing it to be the default browser. I closed Chrome, and opened Internet Explorer which asked if I wanted to make IE my befault browser. I said yes. Closed out of all programs, untinstalled Chrome.

    Problem solved.

  190. Tom Doran says

    that was very helpful. I have to admit, a little worried about downloading a file that was going to edit the registry, worked great!

  191. Chris says

    I found Alan's solution to work. I installed Chrome and set it as default. Then I opened Internet Explorer and set it as the default, and then the links in Outlook worked just fine. Out of laziness I did not then uninstall Chrome, so I can't say for sure that that step is required.


  192. Another IT guy says

    What most people may not understand about Outlook is that IE is the medium behind the application to navigate your mailbox or your local PST\OST files.

  193. Ray Vanderhulst says

    I'm using Outlook 2010 with Windows 7. The only thing that fixed the problem was the Registry edit. Thanks.

  194. Alex says

    I uninstalled Google Chrom and Toolbar, causing hyperlinks in Excel worksheets and Word documents to lead to the error message “This operation has been canceled due to restrictions in effect on this computer. …” My computer runs under Windows 7 (updates current) with IE 10 as the default browser. I use MS Office Home & Student 2010 (updates current). My email is Windows Live Mail, which does not display this problem. Microsoft Fix It 50388 fixed the problem.

  195. vam says

    pure genius! Bless you for saving me a ton of time and aggravation. My links had turned off because of the Chrome install/default/uninstall process as described above. Thank you.

  196. Melvin says

    On registry change, you might need to also change the HKEY\LOCAL MACHINE\SOFTWARE\CLASSES\.html, .htm, .shtml, xhtm, xhtm, etc to htmfile and not chrome... make sure to reboot the computer afterwards.... Thanks for the guide

    • Woody says

      I have this chrome also can or should it be changed or deleted?


    • Diane Poremsky says

      I can't find anything specifically to this key - "OpenWithPrgids" tells Windows to use FF in specific instances. For this reason I would leave it alone, unless you're still getting the error, then rename it to OpenWithPrgids-old.

  197. Joe Marshall says

    I believe that HKCR is a view of HKCU and HKLM provided for the purposes of backwards compatibility.

  198. Skip says

    Thank you too. As usual, the microsoft forums offered next to no help at all compared to a long-tail search of the problem which turned up your solution. 330 comments and about as many 'thank you's' from my quick scan. Thanks again

  199. Joe says

    Used the "Edit Registry Part 2" solution and that worked for me!
    I think I got into this mess when I downloaded an Adobe update which had a Google Chrome option autmatically checked. Although I stopped the Chrome installation as soon as I saw it I guess I wasn't quick enough - it seems that it had already made some registry updates.
    Thanks for the solution.

  200. Ceal says

    Alan's solution worked like a charm. The Junk Mail check box did not. I should have searched the web first when this started to occur, instead i spent months of fruitless efforts trying everything in my Internet security program, in the firewall, in Office, and other arcane places. Thank you much!!!

  201. Ian (NZ) says

    Hi Diane.
    Re the registry fix, I note that it makes changes in a different area to where I would make manual adjustments. The reg fix reads:
    @="\"C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE\" -nohome"
    ...while I'd be making manual changes here:
    [HKEY_CURRENT_USER\Software\Classes\.html], i.e, changing values from “ChromeHTML” to “htmlfile”
    Are you saying that the first "...nohome" command makes those manual value changes unnecessary?
    Computer Guys

    • Diane Poremsky says

      There are two different causes and registry fixes. The first one is for an older problem that is less prevalent these days, the other (chromehtml) for the usual cause lately. In some cases you need to use both (and it doesn't hurt to do both), but whether you use the reg file or edit your self, it would be the same key way.

  202. Ian - NZ says

    Thanks, Diane. Sorry to belabor the point, but I'm trying to explain this to a customer in the simplest way possible.
    Are you saying that, if I gave her your 'nohome' regfix, it would make the manual change unnecessary?
    Or should I be looking for another regfix that makes those manual changes to the second location?

  203. Ian - NZ says

    Diane, thanks heaps. Never got the hang of creating reg files - that'll do the job for my customer nicely. :-)

  204. Ian - NZ says

    Me again with a heads-up. I'd thought, from the customer's description, that it was the no-go-to-link prob caused by the 'ChromeHTML'\'htmlfile' issue.
    Turned out that wasn't the problem. Clicking links just got a long tirade about a missing file association.
    I wasn't sure how to fix this because it wasn't clear just what file association was lacking. In the finish, resetting IE 10 to defaults did the job. There's more here:
    Cheers :-)

  205. hefin says

    tgrf's solution worked for me. Had to go to outlook after my live mail crashed and couldn't even get a new download of lm to work either.

  206. Don Eager says

    Thank you SO much for the Edit Registry, Part 2 solution. I encountered the problem of non-working hyperlinks in Outlook e-mail after doing my monthly system maintain, which included an update to Flash Player. During this update, Chrome was installed. I couldn't see any way to prevent it. Immediately uninstalled via Control Panel, after which links didn't work. I downloaded and executed your "chromehtml.reg" file with instant success. I don't know why Adobe forces unwanted software on you when just trying to keep Flash current. Before I found your site, I tried to fix via Microsoft Outlook Help. Found exact problem, but when trying the "Fix for Me" solution, all I got was a Bing page asking for a search parameter???? Than ks again!!!

  207. Tim Ebben says

    Thanks, that was a big help. Microsoft knowledge base was useless. I will be complaining to Adobe and Google.

  208. M Cragin says

    Using Vista & IE8
    Just wanted to add my hurrahs and thanks to the chorus for Diane's knowledge and Alan's Solution. I read everything and I didn't see anything about using Revo Uninstaller Pro to install applications. It doesn't work if the application/program shuts down your computer before you can save the "log" from the install.

    I had great success with the 2nd Google Chrome install & uninstall after I was able to save the "log".
    Thanks again ending my frustration !

  209. Soozie says

    After weeks of trying to figure it out, I finally found Alan's solution and it worked! So easy! Thank you. I'm a happy camper once again!

  210. Tom says

    Running Windows 8, IE10, Firefox 23.0.1, and Microsoft Outlook 2010. Don't have Google Chrome. Uninstall/re-install of Firefox, then setting as default browser did the trick! While doing that, though, I noticed I could have set program defaults within Windows 8 in Control Manager which also should work. Anyway, thanks!

  211. Israr Khan says

    I am using MS outlook 2007 and i am facing outgoing mail problem , i am sent the message from outlook size is 90Kb but still stuck in outbox not sent yet, my account is MS exchange mailbox and server is on Switzerland, i use my account in Pakistan online
    plz give me help about this problem.
    Israr Khan

  212. Bas says

    I found that going to the IE options, programs tab, and setting the checkmark for the 'let IE check if it is the default browser' also helps. When restarting IE it will notice it is not the default browser and ask if it should change this; awnser yes.
    Thereafter the links in outlook should work....

  213. Ks. says

    I had this problem with Excel when web-links wouldn't open and the same error message popped up. I did have Google Chrome installed, however, as a non-default browser from the beginning, and I went through all steps above - except for the registry change, but nothing helped. What fixed the issue was to completely uninstall Google Chrome. I didn't even have to restart my computer, it worked right away.

  214. jerry says

    for got to add this lol
    If you are using Windows 7 or Vista:
    1.Close Outlook
    2.Open Internet Explorer.
    3.On the Tools menu, click Internet Options.
    4.Click the Advanced tab, and then click the Reset button.
    5.On the Programs tab, under Internet programs, click Set Programs, then “Set your Default Programs”, select your e-mail program and click “Set this program as Default”. Repeat for Internet Explorer.
    6.Click OK and close the dialogs.

  215. Chris Harty says

    The htmlfile download and rebooting Windows 7 did the trick. I have an interview for a Help Desk position on Monday November 25th and Outlook is a main user application at their site. More than likely I'll see problem this again. Thanks... !

  216. Josh says

    Hello. I did the registry fixes as described. That alone did not fix the problem. I am using Vista(sad, I know). After I learned that did not do the trick, for the heck of it, I made IE the default browser and then after that, made Chrome the default again. Guess what? The problem was then fixed. So maybe I misunderstood the directions, but the bottom line is the problem was resolved. Many thanks to everyone who contributed to this thread!!

    • Diane Poremsky says

      No, you didn't misread, but they don't work for everyone. Glad to hear you were able ot fix it.

  217. Rahul says

    Hi there, I think reinstalling Chrome or Firefox is not a good solution. It simply erases stored passwords, bookmarks and lots of other data. Easiest way is to use Microsoft's utility to fix this problem. Just download their Fix It file, and run it. It will fix the problem in minutes without having need to reinstall or importing registry or anything. Here's the link:

    • Diane Poremsky says

      Reinstalling Firefox or Chrome won't erase stored passwords. It's not necessarily the easiest way to fix this problem, but many people prefer doing it because they are comfortable doing it and it works, usually without rebooting Windows. The Fix Its may not work until you reboot.

  218. Christine Beebe says

    Hi I am running Windows 7 with Outlook 2010 and I uninstalled Google Chrome as I did not need it, and when I went into outlook I found I could not open the hyperlinks and I got this message This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator. So after reading all of the above I reinstalled Chrome set it as default browser, then I went to control panel set programmes as default, reset internet explorer as default as all is fixed.

  219. Jim says

    Hi Diane,

    You are a tremendous resource. Thank you very much for your efforts.

    The very simple solution that tgrf provided and that you posted was what worked for me. It certainly was worth the effort to try that first.

    Thank you again, so much!


  220. CJ Johnson says

    Alan's method worked for me as crazy as it all sounds. I did try everything else listed first. Go figure, Alan you rock!

  221. Graphtek says

    This registry mods work with Terminal Server 2008 R2 when removing Chrome without setting IE as default first. Great work, thank you.

  222. Ivan says

    Having problem with links "This operation has been canceled due to restrictions in effect on this computer" with Outlook 2007 and IE 11 as default browser I just make Chrome as default browser an then again IE as default browswr. The problem with links in Outlook vanished.

  223. rollinshultz says

    I encountered this problem with Notepad++ which had been written into the registry as default for html, the above registry change to htmlfile worked after a restart.

  224. User says

    Tried resetting IE; didn't fix it. Tried setting default programs; didn't fix it. Tried registry fix 2; found all values set to CHROMEhtml. After changing to htmlfile, 100% fixed. Thank you.

  225. Mr. Ripdizzle says

    Downloaded the registry keys and installed. After that I tested (without reboot) and the links within the email came up.

  226. Nasser Jamal says

    Dear members,
    My gratitude to all who contributed to solving my M/S Words problem.

    The problem was solved by simply switching to another browser; in this case Internet
    explorer, then redownload Chrome, and there it went back to normal.

    Best regards


  227. Wilson says

    I have encountered this issue and it is due to the registry has been modified.
    Replacing the registry,it works like a charm.
    Thank you.
    So much!

    So very grateful for your guidance. Registry key must have gone missing in uninstalling and updating programs. I followed your link to the Microsoft page and that fixed the problem. Thank you.

    I just experienced this Office Outlook 2010 hyperlink problem since 1 year again. I use Windows 7 64 Ultimate and both Opera Beta (latest) and Firefox (I don't like Chrome), but far-far preferred Opera. I do not know what happened, but since yesterday I get this message. I tried everything ("Default programs" etc.), nothing worked. Then, as a try, I opened Firefox and set "default browser". Office Outlook 2010 error message vanished and everything (Facebook, Linked-in etc.) open in Firefox like earlier in Opera. Afterwards I quitted Opera beta and opened up again and set default internet browser. And know everything opens fine with Opera Beta again.

    That's all Folks!
