As a reminder, the 64-bit client is also considered a beta product, even though you can use it on the live realms. But with that said, most people experience only good things and no real problems with the 64-bit version of WoW. But if you do run into problems, be sure to let Blizzard know about them.
If you have no idea what any of this means, take a look at our brief explainer of the difference between 32- and 64-bit game clients.

A 64-bit client is once again 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). To switch back to the 32-bit client, go into Options -> Game Preferences, and check 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 4.3.3 (15354) (Release x64)
Build 4.3.3.15354 - Windows - Mac

Also don't forget to note this post i made on official forums
http://us.battle.net/wow/en/forum/topic/4079876312#3
this should be fixed possibly later today but meantime, the mac download has to be renamed after unzipping to work correctly with launcher, otherwise launcher will fail to detect it and as such the game preference will be grayed out, and hitting play will always open 32 bit client. You can launch the wrongly named file directly, but that's not recommended as bypassing launcher isn ever good for the usual end user. It's better to rename and fix the issue so the launcher can appropriately recognize and interact with the 64bit client as intended.

Beat me to it. :-)

They may have fixed it, but there was a small bug with the Mac 64 bit client when it was first posted. The unzipped file was named:
World of Warcraft 64.app
but the launcher expects it to be:
World of Warcraft-64.app
The fix is to simply rename the file to have the dash between "Warcraft" and "64".

The main change is the raid-wide buff in Dragon Soul to 10% from 5%.
MysticalOS Feb 28th 2012 5:04PM
the 10% buff has NOTHING to do with patch, that was all baked into 4.3.2. 4.3.3 is strictly client side stuff. the buff is controled at server level, we will not be recieving patches for each stack. it's just a coincidence we got a patch for 10%. The main thing was battle.net updates for their new ressurection program.
cearrdorn Feb 28th 2012 4:36PM
I was mainly looking for what the bug fixes were known to be. IE will i still crash out everytime I'm doing cat druid dps, but can run bear in the same situation without any issues. heh.
Thordred Feb 28th 2012 4:49PM
I just thought I would point out, in case anyone other than I spent 15 minutes feeling like an idiot - this will only work if you have patch 4.3.3 installed. If you're in the US, then what are you waiting for?
If, however, like me, you are on an EU server (other international regions too I guess) then 4.3.3 won't be applied until tomorrow (29/2). So don't try and apply the launcher patch until after your server goes back up in the morning - you will only get an error message like "This beta 64-bit version of Wow does not match the installed version of this game."
Paul Feb 28th 2012 5:28PM
Ah, well this answer my question. I was going to ask if the 64-bit client was only functional on the US version of the game. From your post it seems like it works with any version of the client. Awesome.
Akawaka Feb 28th 2012 6:03PM
You seem MUCH more in the know of this than me and I would so appreciate any advice and clarification from you.
I play on a EU relam and whenever I would download the client from the EU wow site it would only give me the option of my US realm that is closed and inactive. I got a royal ring around by blizz support and even tried asking wowinsider but got no luck. Seriuously I went into all the nitty gritty details and everything is working right but each time only the us realm pops up in 64 bit mode and that acount is closed.
So I was wondering when it it says not yet supported and is technically a beta thing does this mean eventually it will be official and when we go into options then game preferences the choice between 32 and 64 will be there? I also have a 64 bit system with 4 gigs. I am content to wait I guess when it becomes "offiical" I just find all this rather confusing and uber frustrating how it just will not work on my EU account.....
Any words of reason would be uber appreciated!

I deleted the said files. downloaded the new ones and extracted the files into my folder. It wont start, tells me
"this beta 64 bit ver of WoW does not match the installed Ver of the game.
You must acquire a new 64 bit executable in order to keep using the 64 bit, or instead use the 32 bit."
what gives?
dpw15 Feb 29th 2012 3:14AM
Exact same for me :(
WoW Insider are you sure this is for 4.3.3 and not just the 4.3.2 download?
dpw15 Feb 29th 2012 3:17AM
Exact same for me :,,(
WoW Insider, are you sure this is for 4.3.3 and not just the old 4.3.2 client?
Eskarel Feb 29th 2012 8:58AM
To answer the question, you have to complete the update process with the files removed before you add the files back in. Learned this one the hard way.
Johnny.ramos1 Feb 29th 2012 11:12AM
What's the best way to remove the patch so I can redo the whole thing?
Huntrex Feb 29th 2012 6:29AM
Sry complete dumb question - why would I want to run 64 bit? Gosh I feel stupid.
Moonkin Feb 29th 2012 9:17AM
So, I am slow and not computer savvy. I downloaded the client and extracted it into the WoW folder, but when I launch WoW, how do I KNOW I did it properly and the 64-bit client is up and working properly or that it isn't just using the old 32-bit one?

I'm in the US

I've been trying for an hour and it doesn't budge. Help!
