Vista - Trouble installing vista rc1 5600

First Sorry for my english. I download the vista rc1 5600 from the web and i
burn the iso file to a dvd. I tried to install it but i couldn't.

During the first start of windowsafter install i have a problem. There are a
pop-up of windeplay.exe - Bad image that says...

C:\windows\winsxs\..........\comctl32.dll is either not designed to run on
windows or it contain an error. Try installing again...

Begin three or four pop-up appair another one of "install windows" that
says...

windows could not load required file winsetup.dll, the file may be corrupt.
Restart the instalation. Error code 0xC1.

Someone can help me??

Thanks for all
