Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Don't know which one it is specifically, but here's what I saw get installed in this batch:

I now have 3 computers with this issue. The latest one is probably going to have to be shipped here from California so I can fix it, unless someone comes up with an answer that doesn't involve nuking Office from orbit and having to download it. This location's internet connection is so slow it would take a week.
