I just got GTA IV for the PC. My rig is:

CPU: Core 2 Quad@2.33
Memory: 4GB DDR2 RAM
Graphics Card: GeForce 9400GT
Space: 500GB SATA HDD
OS: Windows Vista Ultimate (32 bit).

I managed to isnatll the game's social club but when the game installation starts, I get the error "Your system is not compatible with %p."

I don't have SP1 or 2 yet. Is this the problem or something else?

Some help...

Best idea is go to regedit--Hotkey local machine----system----controlset001---control----search for 'windows'----click in it-------in that there will be csdversion.Double click it.change the value from 0 to 100 .That all save it and restart the computer.Your computer is upgraded to vista sp1.Run setup now.You will be definitely able to play
Thanks for choosing as best answer
