Need help installing

[Shakuris]

So, I have all the files and haven been trying to Daemon tools lite for the ISO. But it doesn't want to work at all. I then used winrar and it seems like it installed but I don't think it did. It asked me to load disk 2, I did, and them back to disk 1. it skips 3-5 entirely. I figured, what the heck? So I removed the files I needed to and copied over all of the Project 1999 Files (V36). I load up the game and it won't let me log in. What happened?
Do I need a good ISO thing? Or did it actually install correctly? What else?
Any help would be very much appreciated. Thank you.
