Launcher cannot read Blizzard updater.

Technical Support
Like the title said.

I had a BSOD while installing the patch.
After it rebooted, I tried running the launcher and it says:

"Blizzard Launcher cannot read the Blizzard updater. Run Repair to get more information about this problem.

So I did, but I got an error saying:

"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."

I restarted and it didn't work. Thinking if it might be a permission issue, I took ownership of the whole WoW folder. Unclicked "Read Only" and it didn't work, just comes right back.

I'm out of ideas on what to do now. Hope someone can help me, I don't really want to uninstall and reinstall the whole thing unless I have too.
