I've been using P6 for over a year now, but never uninstalled my copy of P5 because I've been using its runtime folder in P6 (and i had a lot of trouble with P6 at first).  Does anyone know if I can use windows to uninstall P5 without loosing my runtime folder?  Bassically, will it leave the files i've installed there myself and take alway the system files?  Thanks!
