I've downloaded Red Alert 3 and then I went out and found the official world builder, but during the install shield process of the world builder it has an error that says that it cannot find a legitimate copy of Red Alert 3. I've tried place the installer in the directory of the game, but it still gives me the same error. The game was purchased and installed using the Gamestop App. I have already contacted Gamestop and they referred me to EA support. Does anyone know of a way around this besides buying a disc copy of Red Alert 3?
