Windows SDK for Vista RTM won't install on RC1

I downloaded the new SDK for Vista RTM as DVD image and burned to a DVD. Tried to install on Vista RC1 5600, but Setup.exe fails with "unspecified error". I had the SDK for Vista RC1 previously installed, but completely removed it before attempting to install the new one. I also cannot reinstall the RC1 SDK now. Same error. What do I do now?

I've downloaded the RTM ISO, burned it and am trying to install on RC1. I have a key for all of the editions including ultimate. All of them are being rejected by setup.

I am sure they are being entered correctly but it fails every time. Also the my machine refuses to recognize the DVD as bootable. I have to run setup from within RC1.

I'd appreciate any advice.
