Installing 6.5 alongside Ai6, + sharing VST plugins

Sorry for interrupting the crickets (!) but did anybody installed successfully 2 different versions of Cubase on the same machine? (see opening post)

And how did you set-up your VST plugin folders (.dll files) in order to share your plugins in both versions??

Closing my post quoting Roger Waters, from Pink Floyd’s The Wall:

Is there anybody out there ???
