I am a bit confused. Do you have to use Boot Camp to do the Vista x64 install? I installed Snow Leopard on my MacBook Pro 17. I then installed the update. I installed Parallels 4.0...then its latest build. I started Parallels desktop and then installed Windows Vista Ultimate x64 (SP1). I then installed Autodesk Revit 2010 x64 in my VM environment...seems to work fine (not as fast as I would like but alas OK Is this the correct procedure? Or was I supposed to do something with Boot Camp? I never saw anything related to Boot Camp come up during the installs. Input would be greatly appreciated. Regards, George H
