MoP game not launching - Help

Hello guys,

I've downloaded the MoP client, after changing the compatibility settings for wow.exe (admin rights and as w7) and starting, it ends up crashing with the following error 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"

Any idea how to fix this?

System: Windows 10 pro (no missing drivers / everything is up-to-date)
And the game is not located in C: (boot partition/hdd)

Follow these steps:
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".

"Read only" was causing problems, it's all good now. Thanks for the tip.
