Trying to download WOLK but cant figure out how to do it.

when downloaded it says like divdecoder.II cant be found or something im using bit torrent can anyone help me????

Did you drag the wow icon to your desktop? If so, put it back in the folder and try opening it from there.

i did it said to redownload so i am trying that. forgive the inconvenience my brother and i just wish to play WOLK again after so many years of being out of WoW.
