Ok I am now uploading the new repack. i would delete the repack you downloaded and redownload the same repack the new repack is 89mb I hope it works for you this time.
just remember to install it were your world of warcraft folder is.

my wow folder is default C:\Program Files\World of Warcraft
if you install it some where else just make sure the Core folder is in your world of warcraft folder this is so you can launch wow
This is correct install.
C:\Program Files\World of Warcraft\Core
or any where else \World of Warcraft\Core

Do not install it like this
C:\Program Files\World of Warcraft\World of Warcraft\Core
