insallation problem of call of duty2

dunno if this is in the wrong forum or anything, but ive asked u guys for help before and you were quick and very helpfull.
Ive bought call of duty 2, my sysem spec is enough for it, when it installs it gets right to the very end then just cancells, no error message or anything, just cancells with no trace of the installation, ive tried disk cleanup, cleaned my comp, turned off all runing background tasks n still have the same problem, any help would be great thanks.

 

try posting in the games forum http://forums.majorgeeks.com/forumdisplay.php?f=16 you will get more help there.
