Ok heres my dilemma, Im trying t install Call of duty modern warfare on my computer, except for some reason it wont automatially load the installer program when i pop the cd in. so i go to run, and i typed in setup.exe , and it tells me to go to control panel settings, ive looked throught the entire thing, nothing helped, i decided to go into add/remove progras, i hit add new program, and then aain i clicked add new program from acd or floppy disk, then i get a message saying "windows cannot find the installatin program" and its not the game because it did it to bf2142 or w.e it was, im thinking my computer has like deleted my installer or something,. but i loaded up steam if anyone is familiar with that, and i tlyped in the game code to put my game on steam and it said the code was invalid, any help on the matter would be greatly appreciated, maybe on where i can download a new install wizard or something idk.
