halo2 startup.exe error, win7

hi,
everytime i try to open the halo2 startup.exe application for installation it gives me an error:
"The application was unable to start correctly (0xc0000006).)"
ive tryed different computability modes and running it in admin mode isnt working either.

any suggestions?

Microsoft created the game only for Windows XP.
My cousin somehow is playing that game on Windows Vista. I think with a cr@ck.

Ummm You have that backwards maybe I think
Halo 2 is Vista Only
But Win7 SHOULD Be able to sneak around that with a well placed Compatability mode for Vista SP2

Ops, sorry, you are right. Halo 2 is for Vista only. :P

tried computability mode . didnt work

its playin on my pc without any problem

As I can see there is a deference between your built. shiitzu have you tried it on bult 7600? It may work.

how can i change from build 7100 to 7600>?
