Addon Converter X

Version 1.09

Addon Converter X is a plugin for FSX that makes many add-on aircraft and sceneries developed for FS2004 compatible with FSX SP2 and FSX Acceleration Pack.

Many existing aircraft and sceneries suffer display problems with these FSX versions, such as missing textures or missing scenery objects in the DirectX 10 mode. Addon Converter X resolves many of these problems on the fly, thus allowing you to enjoy thousands of sceneries and aircraft developed for previous Flight Simulator versions with FSX.

Addon Converter X does not modify any files you have installed in FSX. It performs conversions on the fly as FSX is loading files. You don't have to "convert" any add-ons you are installing. Simply copy them into FSX, and Addon Converter X will make any necessary changes automatically.
