We get many questions about Office activation failing:
"After installing and activating Office, Outlook keeps asking to accept the End User License Agreement (EULA)."
This is caused by Windows security and permissions. Your Windows user account doesn't have the necessary permissions to write the activation to the registry.
How to Fix
Method 1: Right click on Outlook.exe and choose Run as Administrator. Accept the EULA. If this doesn't help, use Method 2.
If Run as Administrator does not appear when you right click on the shortcut, use the Start menu or Start screen's Search field to find outlook.exe. Holding Ctrl+Shift as you right-click on the Outlook shortcut you use to open it should also enable the Run as Administrator link.
Method 2: Log on to the computer using a Windows account that has administration privileges. Once you do this, open Outlook using Run as administrator. Now when you accept the EULA, the acceptance is saved to the registry. When you log back into your Windows account, the EULA won't appear.
