Full client wow.exe don't start

Hi guys!

I just downloaded the full mop client, but the game doesent start :/
the wow.exe is running in the task manager, but nothing happens and theres no other .exe file in the folder.

I have win 7 64bit.

What should i do?

I dont want to dowonload the minimal client, my bandwitch is ****ty...

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"

the point (1) it seems silly but you actually have to do it or it will not work
