ACS problem

Been searching for an answer to this problem all day, but am unable to find anything.

Key facts: Using latest version of Windows 10. ACS is installed from an on-prem network file share. Running i7.3.

This morning, a user informs me that ACS is not working. She is getting the error "MSGGEN036 - There was a problem accessing the user product directory".

I'm fairly certain this is to related to us moving her files from a local prem private file share to her Office 365 personal One Drive. We did that last Thursday, and on Friday when she started ACS batch session, it wasn't able to find her individual session files. I had to repoint her batch session to the new location, and after that was done, she was able to work all day Friday without issue.

But this morning, we can't even get the main GUI to launch. I've uninstalled, rebooted and reinstalled, multiple times. Tried 32 and 64 bit. Even tried reinstalling from a different network location. I still get this error.

I'm sure somewhere it's most likely still pointing to the local prem file share which no longer exists, but I don't know where that reference is in order to fix/delete it.

Any suggestions?

Thanks
