I'm trying to install Parallels Tools 5.0 into a BootCamp Vista installation. I've actually not been able to get Parallels Tools working on this since upgrading to Snow Leopard back in the 4.0 days... the ethernet card is no longer recognized, the Wacom mouse no longer works, it's really no longer useable. The installation bombs somewhere near the very end with an assembly error, and then takes forever to roll back. I have in the past tried everything I could find listed here for correcting the problem with 4.0 and was really hoping that 5.0 would fix the problem, but apparently no joy.
