Burn RC1 x86 and x64, run, select upgrade = 0x80070570

So far downloaded/checked both files.
Burned/checked DVD's with no errors.
I run setup from Vista (to upgrade) on the DVD/CDRW that burned the images
and get file errors during install. Put the DVD in my DVD/CD-Rom drive and
have only a readme.txt file.
So far wasted 7 DVD's and a lot of my time - I give up.
I'll stay at Beta 2
