Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey I am trying to install the client for Nostalrius vanilla WoW, and I was following all the instructions of the getting started thread 2.0, including downloading from the correct link and everything.

Well I got to the installation portion and when I try to install it stops me and asks me to insert disk 1, as though I had actually bought the game when it first came out. I do not own any such disk 1 and it will not let me proceed otherwise. Please help.

did you actually unzip the file you downloaded ? i mean open the file you downloaded, moved the files out of that compressed folder and into another folder on your hard drive and then started the setup ?

my friend actually did that...
