Can't Launch World Of Warcraft

Right when i try and run world of warcraft a message pops up saying this [ Launcher requires write permission to the World of Warcraft Registry key to successfully locate and run the game. enable write access to the Registry key using an adminstrator account ] I'm the only user of this computer and i'm adminstrator, i have tried right clicking the desktop launcher and run as adminstrator but still get the same message, also been into the wow folder and changed the launcher there to run as adminstrator and the wow.axe folder..still get the same message.#
