but that doesn't address the fact that I have a valid key. 4 years ago I purchased Office University 2010 and it included a free upgrade to Office 365 when it became available with the option to go back to whatever the current non-cloud Office product is.
Now my sub has expired and any time I open, say, OneNote, I get a popup about needing to renew or enter a key. I tried the University key but its not valid.
How do I continue to use Office 2016? Or was that "offer" non-existent?
Anyone have any insight?
Edit: I'm not looking at continuing Office 365. I'm looking to use the downloaded versions of Office 2016 that are currently installed (via Office 365 subscription which has now expired). The offer I accepted included the ability to continue to use Office even if the subscription was cancelled or expired. There wasn't any indication about how to do this and I can't find any info abou this via MS help. I paid for a stand-alone copy of Office which included an optional upgrade to 365. I am under the impression that I would get to keep whatever version I had currently, not the original 2010 or '13 or whatever it was. As such, I don't believe I need to completely uninstall and install and old version. If this isn't correct, provide me with more than "enter key" or "install from your media" (there is no media, it was digital distribution). I know how this typically works, and this isn't a typical situation.
