Game installation is damaged. Please run repair.

Whenever I try to update wow past 4.0.6 I always get this error in the launcher and I just cant make it go away. I tried to run as administrator and safe mode with networking and it just doesnt do anything. I obviously tried repair and it was useless too.

How do I fix this? been trying to make WoW work for 3 days in a row now.
