I've installed the 64bit version of Windows 7 beta on my MacBook in bootcamp. All runs fine except I get no Aero theme. I ran the rating test and it shows the machine at 1.0 which of course won't run Aero. I installed the Bootcamp drivers from the OSX install cd and two things will not install (Key managemet or something and Apple HAL). How can I get the Aero theme to be available in Bootcamp? Do I need the 32bit version?
