Do you mean you have C12 up and running in Win10 20H2, despite the stated requirements for C12 saying “21H2 and newer” ?
Thanks a bunch for this. Truly saved my mind.

Thank you so much for your issue. I almost re-install all my Windows system due to that problems. THANKS A LOT M. Richyseb
Windows User check if you have admin rights and that the folder is not write-protected, in case that HEYDO´s solution doesn t work.
I’ve tried a few of the earlier suggestions, but had no luck. The only successful solution I found was by adding a Symbol link (Symlink) from the original folder ;
…/common files/vst3
to your new folder ;
./Program files/Cubase 12/vst3/New Folder
The program (Symlink Creator) is free to DL & use.
I am currently using -
Cubase 12, Version 12.00.10 build 247.
On - Win x64 Pro Version 22H2.
Hope this is useful to others.
