Important - This information is no longer up to date. The 64 bit client is automatically included with the game, and can be toggled on/off via the Launcher, if you have a 64 bit Operating System.

Updated for patch 4.3.4

A 64-bit client is now available for use with Patch 4.3.4. 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 into Options -> Game Preferences, and toggling the Launch 32-bit client setting. The game will display which version you are using at the bottom left hand corner of the login screen. ex: Version 4.3.4 (15595) (Release x64)

Build 4.3.4.15595

  • Mac: http://us.media.battle.net.edgesuite.net/downloads/wow-installers/live/WoWLive-64-Mac-15595.zip
  • **Important things to keep in mind**

    If you have previously installed the 64 bit client and are experiencing errors when patching, please refer to this post:
    http://eu.battle.net/wow/en/forum/topic/3389262460

  • The 64-bit client is being distributed separately from the Retail version as it is not yet supported for use with World of Warcraft.
  • Launching the game in 64-bit mode can only be done after patching the game to version 4.3.4, downloading and extracting the necessary files.
  • The game’s built in voice chat does not currently work when using the 64-bit client.
  • [Mac] The 64-bit Mac client does not currently support the in-game movie recording functionality.
  • [Mac] The 64-bit Mac client iTunes' Remote feature does not work at the present time.
  • [Mac] The 64-bit Mac client does not currently support the customized LCD display for the Logitech G15 series of keyboards.

    This is awesome news.
    I have been waiting for WoW to get 64 bit and will do everything with my skills and capabilities to help development.

    Also my first notice of this is atleast slight performance gain, which could be because of more ram available can use little more of ram.

    Bah second :D

    Yep, so far it feels more fluid and like it stutters less going from one zone to another.

    This works fantastic. Before my gpu used like 55% of its power, now its >95% all the time.

    Big FPS gain for me.

    Thank you for a free upgrade

    i used to have unchecked the in-game option "Show Launcher" (this option is no longer here) and now when I execute Launcher.exe, it automatically runs the game thus I cant set the 64bit version :X

    i can execute the 64 bit version without problem but i still wonder why isnt the launcher showing :) is the option whether using 32 or 64 client changing some settings or just runs
    Wow.exe / Wow-64.exe ?

    edit: after running once wow-64.exe, launcher automatically starts executing x64 version instead of x86 :)

    Lol.

    I've watched the difference between 64bit and 32bit in task manager.

    Seems the 64bit version uses 25% less CPU bandwidth.

    It went down from 40% to now only 30%.

    Same fps, maybe a slight faster loading time.

    so far a small "upgrade" for me, though very appreciate.

    Is this just for the ptr at the moment or is this for the actual game now?

    Also why does it say in the first bullet point "The 64-bit client is being distributed separately from the Retail version as it is not yet supported for use with World of Warcraft." What does it actually mean by 'not yet supported'?

    Thanks

    It means that if you experience technical issues with the 64-bit client that you would otherwise not get using the 32-bit client, Blizzard will be unable to provide you with technical assistance and you'll be advised to use the 32-bit version instead.

    And no, this is not for the PTR. This is for the current patch. :)

    Thanks for that. So you can safely go back to the 32bit client if you experience problems? I dont fancy having to do a full reinstall if something messes up!

    Yes, and its as simple as using the tick-box in the launcher. :) Reinstalls won't be necessary.

    Evlhenno: this is Live version of x64 client for current 4.3.2 patch

    its not supported means something like "use at your own risk" meaning that they cant assure the functionality of x64 client.. yet :)

    edit: Danellos youre frickin fast :P

    You keep logging in on the US realms?

    If so go to C:\Program Files (x86)\World of Warcraft\Data\enGB\realmlist.wtf
    (path depends on where you have installed your game.)
    Open that with notepad or something similar and make sure it says the following:


    set realmlist eu.logon.worldofwarcraft.com
    set patchlist enGB.patch.battle.net:1119/patch
    set realmlistbn ""
    set portal eu


    If the problem is what i think it is, then this should solve it.

    Tried using the Nvidia control panel? Not sure on SLi but I have one of those annoying Optimus setups and had to manually tell it which GPU to use with the 64 bit client.
