Flight Simulator x Aircraft Installation

I recently installed Flight Simulator X (Acceleration) in my new computer. In the drop-down aircraft list it shows only one aircraft of each type but none of the different texture that are available for each. The program files show all the aircraft are included. I downloaded and installed three new aircraft and the same thing happened - one texture of each. How can this be corrected so that all aircraft show correctly?

Check the "show all varients" box at the bottom of the selection screen.

Of course!!! Thanks for your help.
