I WANT TO PUT CALL OF DUTY UNITED OFFENSIVE BAK ON MY PC BUT FOR SOME REASON THE PROGRAM IS STILL IN MY ADD/REMOVE PROGRAMS AND WHEN I TRY TO UNINSTALL IT THE INSTALL SHIELD ONLY GOES HALF WAY UP AND THEN STOPS. THIS IN TURN IS CAUSING THE GAME TO THINK IT IS STILL ON THE SYSTEM WEN I TRY TO INSTALL IT AND IT SAYS PLAY GAME OR UNINSTALL INSTEAD OF INSTALL... I HAVE TRIED LOACATING THE FILE MANUALLY BUT THERE IS NOTHING I CAN FIND ON IT.. PLZ HELP AZ I CANOT PLAY THIS GAME UNTIL IT IS SORTED.
