We have released a tools patch that updates the Repair utility. Previously, the repair utility would not revert the game properly if it found damaged files and would cause patches to fail. To get this patch, please start the game and try logging on.


If you're receiving a failed to apply patch message, please check the following:

If you're running Windows Vista or Windows 7, you may have to right-click the game and start it up as an administrator to get write access. If that does not work, try checking your internet security program first. If you have rules in its program list to let it through, go to Internet Explorer -> File, then make sure Work Offline isn't checked. Also check Internet Explorer -> Tools -> Internet Options -> Connection -> LAN Settings and make sure your proxy information is correct. If you don't use a proxy, make sure that everything is unchecked and hit OK. If that doesn't work, go back there and try toggling your Automatically detect settings box, then hit OK. Try the game again.

In rare cases, you may not have proper permission to write to your World of Warcraft folder. Creating a new Windows user account with administrative rights may allow you to run and patch the game.


If you're receiving a Unable to validate game version message, try closing the game and restart it.
