Problem with Command & Conquer: Generals & VISTA

I installed the game successfully (at least thats what it looked like)

When I press PLAY it hangs on the start screen.

This also happens with GENERALS as well as ZERO HOUR

I am running VISTA Premium

System Specs are:
CPU: INTEL CORE2 QUAD Extreme
Mobo: ASUS Striker Extreme
Mem: 4GB (1GB x4)
GPU: ASUS NVIDIA EN8800GTX/HTDP/768M
HD: 4 x 120GB SATA drives in Raid 0+1

It worked fine under XP for the same system.

Any ideas?
