I cant play any games on Vista SP1 64

[Heat20]

Hello, i have installed vista sp1 64 version and i have been trying to play alot of games recent once, and they always dont get installed for some reason.
games such as BioShock 1, Tom Clancy Endwar, Flashpoint Dragon Rising and more more games, Now why is this happening?
the reason for me installing Vista x64 is to be able to utilize all the 4GB RAM and i have about the improved performance of x64 over the x32.
so what is the solution to my problem ?
