Cd Key For Flight Simulator X I Lost My Flight Simulator X Disks. Options?

I lost my Flight simulator X disks. Options? - cd key for flight simulator x

I really want to play my game Flight Simulator X, but I have my game discs. I have always been the case and still have your CD key, but not play. Is it possible to download an installer for the game and just type your CD key, so they know that I bought in the past? Is there anything I can do to the game again to play without buying a new shop?
