I play WoW sometimes on my laptop, through an external hard drive. Whenever there's an update I get this message, and the only way I can fix is if it I download an patch the WoW Client on my main computer, then transfer the whole game back onto my external drive.


Anyone have any idea why this happens?

Hi Zersetzen,

It just means your registry has no idea where the game is at. Please check the sticky thread. 4.0 / Cataclysm System Requirements
