Patch 4.3.3 breaks the current 64-bit WoW client

While many people have enjoyed the splendor that is the 64-bit client for World of Warcraft, it seems that the upcoming patch 4.3.3 is going to break it, forcing users back down to the 32-bit client.

Relax bro, the 64-bit one is still in testing.

  • WoW-64.exe
  • MovieProxy.exe

Then download this and extract to your WoW folder (notice this IS AN OFFICIAL media link):
