My Microsoft Office Home&Business 2013 stopped working all of a sudden. I checked out on Support what to do and I had to download FixIt program. It uninstalled Office, and that's it. Now, I have to install Office again. I have product key but I've lost/forgot Microsoft Account's user name (and password) and there is no way to retrieve it back. So, I created new account (this one) to try and download Office from another account, but there's no way to do it because product key is stitched to another account.
My questions are:
What to do?
Is there a way to get Microsoft account's user name through MS Office product key?
Is it possible to retrieve account's user name, and how to do that?
