Launcher isn't opening

Data/EnGB/wow-update-engb-18273.MPQ: World of Warcraft cant make a required change to an archive file. Be sure you have write permission for the World of Warcraft folder or try running in administrator mode.

I downloaded the full game from your site, tried to start the launcher and this is what pop-ups, the game is in processes in task manager but not starting. Help me ?

1) close your Torrent client and move your WoW folder away from your Torrent's download destination
2) now right click on WoW folder> Properties> remove "read-only"
