Ultimately, it is possible for every one I tried. I found that, in order to make these AddOns think that specific flight simulation software is installed, I needed to modify the Windows Registry. While this is up to the developer to offer, I wanted my existing AddOns to work with my older platform, P3Dv3 (not P3Dv4).


These AddOns include everything from aircraft, terrain, airports, weather, services, scenery, navigation, and more. For example, they may support Microsoft Flight Simulator X (FSX), but not Lockheed Martin Prepar3D (P3D) or Dovetail Games FSX Steam Edition (FSX:SE). I have noticed a lot of aftermarket flight simulation AddOn installers that only natively support maybe one or two versions of the popular platforms out there.
