Blizzard Updater failed w/Internal Error

Mac Technical Support
While trying to patch today through my wow launcher i get the message "Blizzard updater failed with an internal error". Patch 4.3.2 i switched to 64 bit, wondering if that has anything to do with it. Also tried some of the troubleshoots in this forum with no fix.
Edit: Using windows 7
It is the 64 bit. Fixed it for me when nothing else did. http://us.battle.net/support/en/article/64bit-client-prevents-patching-to-433

These guys are 100% on the right track, I went ahead and deleted the the newest update.final. item so the updater would run the repair tool after also deleting the 64 bit client and downloading the new one. Wait til the updater completes, install the new client, play the game. Simple!

Thank you to the "Blues" and the "Community" for posting, figured it was the client but you guys saved me the headache and time of tracking down the problem.
I am also getting this error. Was working fine yesterday. Tried all the suggestions
and nothing is working.
I don't have 64 bit... still wont update for me. Very frustrating. Someone please help?
We've never had the 64 bit test client installed. We've been getting this error since yesterday. I've tried the various suggestions in the other threads to delete various caches and such but to no avail.

Help.
Hmmmmm.....

I need some data off the people getting the internal error who don't have the 64 bit client installed.

Can you guys take screenshots of your Wow folder , Data folder and Updates folder showing file sizes and modification dates ?

Then upload them somewhere. A zip of your Logs folder excluding the chat log would be nice as well here.

As well as a copy of your launcher.wtf

I need some datas to solve this.
