Prepar3D Installing Add-ons Questions & Answers

Prepar3D add-ons may use traditional installers, the scenery library or the newer add-on.xml method, and choosing the wrong approach can leave aircraft, gauges or scenery missing. This hub covers installing Prepar3D itself, adding aircraft, configuring weather engines and SimConnect components, and setting up orthophoto scenery without disrupting default files.

Answers written and tested by the Fly Away team address version compatibility, licensing, folder permissions, scenery priority and add-ons built for older Prepar3D releases. They also explain how to locate configuration files, verify required runtimes, remove packages cleanly and troubleshoot common symptoms such as invisible models, black gauges, missing textures, duplicated scenery or weather software that cannot connect to the simulator.
