Recently I encountered an odd problem activating Microsoft Office 2016 on a Windows 7 sp1 (64 bit) computer. The activation window would pop up after opening Word, I’d enter my Microsoft Account username and password (which had valid Office 365 device licences) and then the window would just disappear. No error, nothing. Office would remain not activated and the next time an office program was opened the activation window would pop up once again.
The solution, for me, on this clean install of Windows 7, seemed to be running all windows updates which included the installation of Internet Explorer (IE) 11. Previously the system had Internet Explorer 8 installed. Since around 100 updates were installed all at once I can’t say for sure that it was the IE update that did it, and I’m not going to go back and test it further, but if you’re having a similar issue give it a go:
- Make sure Internet Explorer is up-to-date.
- Make sure you’ve run all the latest important Windows updates.
