I’m using SketchUp Pro 2022 on Windows 11.
I have software (indigo renderer) which is looking for the appropriate folder to install its extension and related files. It doesn’t use an RBZ.
I tried the suggested path to no avail:
C:\UsersXXX\AppData\Roaming\SketchUp\SketchUp 2022\SketchUp\Plugins
The extension installs okay into there but then is not available within SketchUp.
