Nostalrius Begins - Quality wow vanilla realm (1.12)

When i open the game it says that the failed to open archive texture.MPQ , someone help ?
EDIT : I tried reinstalling the game and now when i try to open the setup it says : Windows cannot open the specified path , program , etc . You may not have the permission necesary to do this , says the same thing if i run as administraitor .
EDIT : Downloaded the mega link file and it works fine now ^_^

Got same problem, except mine doesn't get fixed by using mega link instead of docs link, any help?

As much as I hate to say it, you may have to download the installer again in case if your download was corrupted. You could try running the installer as administrator to see if it's a permissions issue preventing you from installing it.

Yea i found a better solution , go to the page from wich u get the downloader (Norkan's page not the begginer page) and go at the 8th page , there is a guy that has a torrent download , download that , put it in your torrent after it's done extract it and you will have a wow folder from wich you need to open up realmlist.wtf(i think its .wtf) and then change it to ''set realmlist login.nostalrius.org'' and then you open WoW.exe and u can play ^^ , no installation required .
