Installing add-ons can involve more than copying a folder. This hub covers FS2004 installation on modern Windows versions, Prepar3D scenery and aircraft paths, add-on configuration files, library ordering, permissions and compatibility. It also explains what the Prepar3D SDK contains, when it is needed and how its tools fit into development or troubleshooting.
Fly Away team answers address recurring problems such as missing scenery, duplicate entries, add-ons installed into the wrong directory and packages that worked before an update. Guidance also covers sensible backups, clean removal and keeping third-party content separate from core simulator files where possible.
