I think I’ve maybe had this happen when the plug-in is in use in a host, like a daw, while attempting to copy.
Yeah, that’s right. I believe you need admin permission to write to that folder, so you should set the plugin copy path to your user VST folder or change the permissions on that folder.
I just disabled the Enable Plugin Copy Step setting to solve the issue probably should grant some admin permission to the folder like what you suggested.
edit sorry, I thought you were talking about Apple.
