Just a heads up everyone.

The next time you run my WoW Launcher you’ll be prompted to update. This update includes support for the 64-bit version of the game.

If you have the 64-bit binary files in the WoW directory, and through the official WoW launcher have it setup to not use the 32-bit client then my WoW Launcher will run the 64-bit version instead. If the 64-bit version does not exist, but it’s setup to use the 64-bit version, it’ll use the 32-bit version as a fallback.

This only matters of course, if you do not use the “use Launcher” option.

Have fun!
