Cannot Create Soundtoys: Version Root Folder At Soundtoys 5 Link

The error means:

: C:\Users\Public\Public Documents\Soundtoys\Soundtoys 5 . Mac Presets : Users/Shared/Soundtoys/Soundtoys 5 .

If the method above does not work, or if you prefer to keep your plugins in the global Library folder, you may need to grant the installer "Full Disk Access."
