Hi @DEMdev
I am not an admin in my environment (unless I elevate to admin) and neither are my users. And I am not elevating in this case.
As a test, I completely deleted my profile and logged in, basically as a new user. ADMX policy to prevent editing the registry is enabled and allowing registry tools to run silently is enabled.
I turned debugging on and I found in the log that regedit is in use successfully;
2021-02-08 11:58:52.603 [DEBUG] ImportRegistry::Import: Calling '"C:\Windows\REGEDIT.EXE" /S "C:\Users\User1\AppData\Local\Temp\FLX5AD4.tmp"' (RPAL: l=0 (F/E), r=1)
2021-02-08 11:58:52.654 [DEBUG] Read 1 entry from profile archive (size: 700; compressed: 288; took 58 ms)
However, further down the log, I see that I am still getting the error when launching Chrome
