Call of Duty 4 error in Windows 7

I installed call of duty 4 on my hp probook 4530s i3, 500gb, 4gb. However when I tried to run it it give the following error

"iw3sp.exe has stopped working"

Can anyone please kindly tell me the solution to this problem. I shall be very thankful. I really want to play this game.
