I'm getting an error while trying to start up the game

I am getting some sort of an error wich is sort of weird to my cause i have previously played the game on this very PC and on my previous PC also and i am sure that i am complitly okay with the hardware requirements for this game still i have downloaded it a couple of minutes ago and i tried turning off the anti-virus and the firewall giving the administrators permission and all the i'm familiar with in the past while having a problem with getting a game to work but this time i cant seem to figure out the solution to this problem so any help would be very much appreciate.
I am providing a screenshot of the error that popped up while trying to run the game on Windows 10 x64 bit: http://prntscr.com/edl414


The text of the error if you don't want to look at the link:

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

Thanks in advance.

Follow these steps:
1) Restart your PC ( this is really important)
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".

Ye it was the removal of the "read-only" feature on the folder i was doing it only on the launcher it self, thank you for your help!
