MoP doesn't start at all, get an error

So, I downloaded MoP yet again, but this time, everytime I start it I get an error :
"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"

Tried a lot of things but none of them work, even redownloaded the game and it didn't help.
So if someone knows how to fix this, please help a man out :)

Right click on MoP folder>Properties> disable "Read-only"

done that before as well, doesn't work

Restart pc, move your game folder somewhere else and do the steps I told you before.

Thanks, can't believe something this easy worked...

Haha that is true, sometimes the issue might seem big but to solve it, it's actually quite simple. Glad it worked for you tho.

Take care buddy.
