I figured I'd ask the question that's probably been asked too many times: does Parallels work with the brand new Pre-RC1 build of Vista? I guess I'm trying to throw this out there so that I don't wonder every time a new build of Vista comes out.
The answer, as always is no. No new version of Vista is going to make it work. It is not something that must be done to VIsta. Parallels must ad ACPI support, which is slated for their next MAJOR release.
The latest beta of Parallels has Vista support, albeit just for Vista B2. They have RC1 working on an internal build and will be available in the 2.2 release version. And to the original poster, there are already 3 threads about this in the forum.
