How do i completely uninstall Ultimate 2021

[Greyfox]

....Is there a way to completely remove any trace of 2021 to try again?

Safe way - use the uninstaller that came with U2021
Option: Depending on how you view the use of clean up software, follow up standard uninstall with CCleaner - relatively safe

Alternatively use uninstaller software like Revo Uninstaller Pro. Various scan options with different risk levels

Another alternative is to manually search drives and registry for U2021 items. Don't attempt this unless you are completely comfortable working with the registry and have a proven recovery system.

Okay after some fun and games trying to run both the database and my pictures from Onedrive, (believe the issue is due to the fact that one of the PC's has onedrive installed/stored? on a drive called D:\ instead of C;\

I've given up and gone back to Ultimate 2020 and a working database. Now every time that i convert the database for Ultimate 2021 I become unable to store only keywords on my pictures. Embed metadata throws up an error.
