My first installation - installing 2007 on network

Hello,
I have been asked to install Solidworks in an environment thatcurrently has Solidworks 2007. There are 2 users running SW 2007with a 3rd machine acting as the license manager. I want to addanother workstation but when I install from the CDs I cannot findhow to "tell" the installation that I am using a license manager.

What is the proper way to install SW in an environment like this?

Thank you.
