I installed Call Of Duty onto one computer and lost the cd when I went to install it on our new gaming computer so i copied the install dir.
I recently got the United Offensive expansion for it but cannot install it due to a bad installation.
The error messages words are:
Setup could not locate a valid installation of Call of Duty
Call of Duty must be installed before installing Call of Duty United Offensive
Click OK to exit installer
I am thinking maybe its missing registry entries? Although the game, single player and multiplayer, work fine... Also it still has its cd-key there.. (I know because it tells me when I look through the multiplayer options.
Any help would be greatly appreciated!
