World of Warcraft patch 4.3.2 64-bit client download and information [Updated x4]


As we posted earlier, Blizzard has released the information necessary to get the 64-bit client up and running with the live patch 4.3.2 servers.

Please remember that this 64-bit client is still in beta, even though you can play the live (non-PTR) game with it. This means that you might experience unexpected crashes and other bugs. Be sure that if you do experience them, you report them right away so Blizzard can fix everything up.

I've installed this live 64-bit client; however, there still seems to be a version validation error with the servers. This is probably a quick fix that Blizzard can take care of, and we're hopeful that everything will be solved soon.

Download the Windows client here and the Mac client here. The full blue post after the break.

Update 3:10 p.m. EST Blizzard pulled the download information from its support forums and posted a message saying that final preparations were being made and the client would be up soon. We're assuming this is due to the validation errors with the servers. We'll update this post when we know more. The download links and everything still work, however.

Update 4:05 p.m. EST Blizzard posted an update this afternoon:

Omrakos (Support Fourms)
The 64 bit client for the live realms isn't ready to be used yet. For now, set the game to use the 32 bit client. This is done in the Game Preferences in the Launcher under Options at the top left of the Launcher screen.

Update 6:20 p.m. EST The 64-bit client will not be usable today, due to unforseen issues. We're leaving the original blue post with the download links up after the break.

Omrakos (Support Fourms)
Despite our best intentions and efforts, there are some unforseen issues preventing the 64 bit client from being made available at this time.

Update 2:40 p.m. EST on 2/1/12 The 64-bit client is now functional.

Omrakos (Support Forums) -- World of Warcraft 4.3.2 64 bit client
A 64-bit client is now available for use with Patch 4.3.2. Before being able to launch WoW in 64-bit mode you will need to download the 64-bit client for PC/Mac (using one of the links below), and unzip it into your World of Warcraft directory. Once you extract the files you can start the 64-bit client by opening the Launcher as normal (Run as Administrator if applicable), go intoOptions -> Game Preferences, and toggling the Launch 32-bit client setting.
