Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
RegClean would have not fixed this problem, let alone JV16, GLARY, Advanced uninstaller pro or any other program with a Reg cleaner. Turns out after investigation, the security on the FOLDERS were corrupt and not set correctly. I checked the log files and it was ACCESSED denied. So I changed the security and ran a program that completely removes Any traces of OFFICE just to be safe. I did compare these folders a different computer and saw the difference. Not sure what changed this, but I have seen it before for another program.. I believe this issue was with Windows upgrade assistant too.. Seems to be an issue with MS Op systems-- some kind of bug.. Shame Microsoft doesn't fine tune their existing OS and remove the bugs, but instead, keep on add more stuff to a buggy OS....
Seems the MS website was buggy by the triple posting.. I have had that problem too..
