Having trouble installing sims 2?

When I put the Sims 2 cd in my computer, the options pop up view folder, import pics etc. The only option that makes since is brows folder. When I do that it takes me to cd where it says ASPYR GAME AGENT, LOCALIZED, SUPPORTLOCALIZED, THE SIMS 2 READ MEAPP, and THE SIMS 2LOCALIZED. I dont know how to install the game from this point on.
