The easiest, least confusing way to corral your soft synths is to have their .dll files all in one VST Folder as a sub-folder in your Cakewalk master folder. When you're installing a VST, it usually finds your One VST folder, and will ask if that's where you want the VST .dll file.
When you have a VST that doesn't have that as part of the installation dialogue, then you just watch where everything is installed, then move the .dll file yourself to your master VST folder. That way you don't have to keep adding to a list of scattered folders all over the place with your VSTs, -no need to add a new location to the plug-in manager.
