Ciao Umberto,
After trying many times to run P3D and getting ntdll.dll fatal errors, I uninstalled KIAH, GSX, your download manager, COATL engine and now the sim starts and runs. I still have your CYVR, KLAX, KLAS, KORD, PHNL, Hawaii vol 2, KFLL, KJFK v2 installed
Could you please tell me how to correctly install your add-ons so I can run my sim?
I already know about disabling anti-virus and firewall, so I can only conclude there is something in the SODE part of the add-on that is not working correctly.
I have been a long time supporter/ purchaser of your airports and would just like the sim to work.
Thank you.
