Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I unzipped the .zip file and got to the folder, but I cannot launch the patch. It says "The Blizzard Launcher cannot start up The file "/Applications/World of Warcraft 1.12.1 OSX/World of Warcraft.app" could not be read. If this problem persists, you may be able to solve it by uninstalling and then reinstalling the game. If you are unable to correct this problem, please contact Blizzard Technical Support. (GetVersionDataMacOS)". Can someone please help me?

As for me, client version on this forum was incompatible with macos 10.10.3 Yosemite. So i had to find another version and got it on thepiratebay. https://thepiratebay.se/torrent/6774094/Mac Just click green Get this torrent sign.
