Did you happen to download the 64-bit version, Vista x64,
and your computer does not have a 64-bit CPU?

I received the same message when installing the 32-bit edition from within
Windows XP Home Edition. It went through the entire install then gave that
message after the final reboot. RC1installs just doesn't always work. This is
the first RC of any software I have ever tested that couldn't even be
installed. Bummer!
