Just downloaded the game but won't open

Hey everyone, I was wondering if someone can help me. I just downloaded the game using bittorrent however whenever i open it it won't let me. It says:

"Data/enGB/wow-update-enGB-18273.MPQ: World of Warcraft can’t make a required change to an archive file. 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"

Someone please help :)

Have you tried to run the game in administrator mode? Also make sure the folder has 'read only' unchecked. also try putting the folder under Program Files not Program Files (x86).

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