Can't open wow.exe 5.4.8

[fredrik980326]

Hello there, well as u read i can't open wow.exe and the only thing that pops up is this...

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

For some reason i can't wrap my head around this one :/

So if any1 know how to fix this id be very thanksful :)

(just downloaded the windows 5.4.8 mist of pandaria client)
