PLEASE HELP... I am new to all of this

[Ronin1272]

I recently acquired Age of empires II and the expansion form my cousin in law. I found this cool website and got a link to gamefix.com. I downloaded the no cd-launch thing but cannot figure out what to do with it. Any suggestions? I downloaded the one at the top, submitted march 2002, apparently it was the latest version, but I don't know where to put it or do with it. Sorry for my ignorance, but any HELP would be greatly appreciated.
