I've tried for days now to activate my stand-alone version of Word 2016 in Windows 10, which until recently was working fine. Then, for some reason, it wouldn't launch. That led me to many and various ways of uninstalling and reinstalling Word 2016: streaming,

When I run the activation troubleshooter, I usually see this:

But regardless of whatever I do, Word 2016 will always return the first error that it can't find the license.
