Just upgraded my Office 365 ProPlus installation to the new Office 2016 on my computer and noticed that my installation didn’t want to activate when I started up my Office applications. Since I am running Windows 10 and insider I tried the mobile apps and they where running perfect. So there have to be something wrong with my computer, and started to search the Internet if someone noticed the same issues and yes there are.

We’re sorry, something went wrong and we can’t do this for you right now. Please try again later. (0x8004FC12)

I haven’t been able to test the upgrade on a Windows 10 without insider.

[Update] Some folks told me that a Quick Repair from Control Panel > Uninstall or change a program will do the trick, but either this or the Online Repair worked for me.


The solution I found is not nice at all but it works, and as I understand there are some Windows 10 settings that conflicts with the Office activation.

First change some registry keys, that should already exists


NoAddingComponents change from 1 to 0


NoActiveDesktop change from 1 to 0

NoActiveDesktopChanges change from 1 to 0


Run the following commands from an elevated command prompt

net localgroup Administrators LocalService /add

fsutil resource setautoreset true C:\

netsh int ip reset resetlog.txt

And now you have to restart the computer and launch the Word elevated as an administrator.

An activation should appear with the text “Activation was successful”


I just hope this is a temporary problem!
