So, I decided to start playing Quake 2 as I saw it was on Steam, I used to play it a long time ago, but not really when it was released. I bought Quake 2 on Steam and today I found Quake 2 Ground Zero laying around in a game store so I bought it. Now, First of all, does Ground Zero even work with Steam Quake 2? And the second thing is, when I insert my Ground Zero CD it just leads me to Itunes to download the audio (wich is really great as all of you know). I went to DVD and clicked open, that lead me to some files named "Data", "Install", "Splash", "AUTORUN" and "setup" I naturally clicked setup wich lead me to a setup wich gave me three options, Install, More and Quit. Again, I naturally click Install, nothing happens and the setup freezes. So, the splash program does not work. I click on the install folder and finds a program named "setup" It tells me to approve the use of it as an administrator (that came out weird) and I clicked yes. Nothing happens. Does anyone know how to help me? I really like Quake 2, it's amongst my favorite games I think, and sorry for my horrible English. Please help!
