Hello, I just finished downloading MoP 5.4.8 and I tried running it (wow.exe). And I get the following message :
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
I tried running as administrator, disable both antivirus and Windows Firewall, nothing helps.
1) close your Torrent client and move your MoP folder away from your Torrent's download destination
2) now right click on MoP folder> Properties> remove "read-only"
