Hi. Please do not add "C:/" as your plugin install location. That will cause long load times, if not a crash. Personally i recommend setting up file folders for your VST plugs to be installed in. For example [c:/user/me/recording_software/plugs/vst.] Then you need to copy this address as plain text and add this text to your plugin locations under set-up. Now, if you are using vst3 plugs, they tend to install to [C:/Program Files/common files/vst3]. F.Y.I. - not sure this is relevant to newer versions of Studio One but adding [c:/Program Files] as your search location can cause crashing. Also, please make sure your plugins are the current updated versions.
