Excel cannot open or save any documents

[JJs-Code]

I recently updated MS365 to the latest version, today I started getting the following message, on excel only:

"Excel cannot open or save any more documents because there is not enough available memory or disk space"

I have tried all manner of solutions on the internet, including turning off protected view and doing a repair of MS Office, among others. I am now starting to wonder if this is a simple issue with Microsoft-Activation-Scripts not being supported for updates. Once I've activated office can i update as i please do i have to stick with the version i have? I have tried running the activator again but this doesnt seem to fix the error.

Do i need to uninstall and reinstall using the version links provided here? Going mad, i havent been able to do any work today because of it.

I would suggest completely doing a full reinstall using office scrubber but maybe the devs over at the discord server have a better way to fix this

so to answer my question am i right in saying that the latest versions of office arent supported? also what is office scrubber? i havent heard of that and i cant see it on the github page?

I have fixed the issue, it was nothing to do with activation. for some reason the cache location had changed on my system to a location that no longer existed, i updated this in the registry and the issue is gone. for those who want to repeat the issue, here is what i changed:

In the Registry Editor go here: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

Check the 'Cache' entry, does the path it has saved exist? or is it showing a weird path doesnt make sense?

change it instead to the following: %USERPROFILE%\AppData\Local\Microsoft\Windows\INetCache

interesting fix, the update might have fucked that registry up
