patch won't install?

Just downloaded the Wrath of the Lich King client, but once it started it told me there was a patch, after I downloaded the patch, I got a window saying " World of Warcraft could not be found. To continue, please browse to your World of Warcraft Installation directory." I don't know where to save this to or how to fix this issue, if anyone has any suggestions?
