After running Office 365 on my Windows machine for several months, a notification popped up saying that I was using an unauthorized or expired license. I was completely confused because I knew my license was legit and other machines that were using the same license seemed to work fine. After several hours of struggling to find the solution to my problem I stumbled upon this page by Deploy Windows.
I tried reactivating my license only to get an error that says:
We’re sorry, something went wrong and we can’t do this for you right now. Please try again later. (0x8004FC12)
The solution as explained by Deploy Windows is to do the following steps:
- Change the NoAddingComponents registry key from 1 to 0 under HKLMSoftwareMicrosoftWindowsCurrentVersionPoliciesActiveDesktop
- Change both the NoActiveDesktop and NoActiveDesktopChanges registry keys from 1 to 0 under HKLMSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer
- Open an elevated command prompt and run the following commands:
net localgroup Administrators LocalService /add
fsutil resource setautoreset true C:
netsh int ip reset
- Open up one of the Microsoft Office applications and it will say that “Activation was successful” and then relaunch the Microsoft Application again and everything should work.
What a headache but now I can be productive again.
