Missing files Groove Agent SE after update and/or installing packages

Hello sundqjan for your detailed explanation. The two files that you mention are exactly the same that are missing in my system. But I can not find them in the alternative folders that you did. I believe these files were installed in these folders in your system only after you did the full installarion with the Cubase 10.0.30 installer. I guess I must do the same. Until I understand, you uninstalled only Cubase files and the external VST you left untouched.

Little detail only, for the full 10.0.30 installer I must download a 21.13 GB file.

I will report here the result.
