I tried opening my 3.2.0.10314-to-3.2.2.10482-enUS-patch and it said the following. "This update requires "World of Warcraft.app" version 3.2.0.10314. You have an older version, 3.0.1.8874." Wrath of the lich king is installed, and, to my knowledge, is not updated to 4.00 or over. If it helps any, I'm using a mac-OSX.
It would appear that the version the patch is finding is 3.0.1.8874. If you're using multiple WoW folders it's possible that the patch is choosing one over the other and you could try to fix it by putting the patch into the folder you wish to patch up and/or renaming your CoTH folder to "World of Warcraft" (this should definitely work if your CoTH folder is in the same place as your normally installed one).
Problem is resolved. Thank you!
