I bought FSDT GSX and airports (KLAX, KORD, KMEM, KJFK, KDFW and Zurich) for FSX before and now would like to install those to P3Dv4. But after the installation to P3Dv4, message “Active but not installed in Scenery Library” show in addon manager for all FSDT airports, except GSX 1 is active and GSX 2 is in trail mode. I tried uninstall/reinstall dozen times but no work. Deleted/replaced bglmanx_fsdt.dat still changes nothing. Antivirus and firewall were off during the installation.
Curious thing is P3Dv4 can detect FSDT airports in add-ons and sceneries (in grey line), but addon manager cannot. When I deactivate those airports in addon manager, uninstall and reinstall again, the status in addon manager shows “Not installed in scenery library”, not in trial mode. I think something wrong in addon manager.
Please advise any solution can solve the issue, thank you.
