Be sure you have write permission for the World of Warcraft folder or try running the game in administrator mode. For more information, see: https://battle.net/support/article/6910

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"
