Mac Client WotLK download/launch issues

So, I downloaded the Mac client for WotLK from the link provided, moved the folder into the Applications folder, and the World of Warcraft icon has a slash through it and I get an error message that says ' The Application "World of Warcraft" can't be opened. '

Any thoughts as to what I might have missed? Suggestions? Etc.

Thanks in advance!
