Hi Nico,
unfortunately no success, I even copied IVA_MTL into the Prepar3D V5 Main Folder: f:\Prepar3d v5\IVAO_MTL2, unfortunately no success either. The automatic scan simply does not find the AI aircrafts. All folders are shared in Windows 10 Pro.
Manual installation does not work either. I have added the line <parameter name="lfolder0" value="F:\Prepar3d \IVAO_MTL2" /> to the end. Does it perhaps need to be inserted in a different place?
I hope we get the problem solved, because without your tool the sim is much more boring.
Kind regards
Peter
