Vista RC 2 fails to install on my PC :-(

Just when I wanted to test the newly-downloaded Windows Vista Release Candidate 2 (build 5744) on my VMware Workstation, I noticed it failed to install. :-( The problem is a missing CD/DVD driver which sounds a bit odd in my opinion, but that's what Vista keeps telling me:

"A required CD/DVD drive device driver is missing." Hopefully, the RTM version will work better. Until then, I'm going to stick to my RC 1 version.
