Simple question for the professionals

I downloaded a .zip for the Twin Towers. I want to put them into FS2004. In the folder is a utility (?) from Abacus EZ-Libraries that I think is supposed to help in doing the installation. I ran it. Now what? How do I get the WTC files into the scenery of FS?
I got it! Now it looks like I remember seeing the real thing, except I think they should be a bit taller. Do they look right to you?
