WE FINALLY managed to get a copy of both Windows Vista RC2 32-bit and 64-bit computing. You can read what happened when we tried to get the 32-bit version, here.
The 64-bit code that I am running on another machine simply refuses to run most of the demos and benchmarks that we tried.
So, if you want to play games you'll have to play with the 32-bit edition first. Using this, we managed to install Steam and Counter Strike Source and Half Life 2 and it works well, including some other Steam games but, for example, Reality Mark won't work, Cell Factor demo won't work, Battlefield 2141 demo won't work.
