You DON'T have to re-install.
Just create a folder (and sub-folders if you like).
TRackS CS is what I used (and re-named the old install TrackS OLD).
These folders can be anywhere you like, just let Sonar "know" (in Plugin Manager) where they are.
I have lots of folders & sub-folders in the main "Vstplugins" folder.
Easier (for me) than using the Plugin Manager organizer.
Waves is the only one that I can't "fix".
It installs one dll that is a "shell" of sorts; I guess.
Don't forget to "re-scan" after any reorganization so Sonar knows where to find everything.
Then its a good time to burn a new "image" of your OS drive.
I NEVER install anything without burning an image; bread crumbs to find my way home...
And burn again if I'm happy with how things turn out.
HTH,
Tom
