I have the latest (0.92) Headwind A330 in my community folder, but the airliner doesn’t show up in the game. Content manager sees it but says not installed. Nothing else is in the community folder.
Have you tried to reload the Sim? If you put it into community folder when the Sim is open it won’t install the mod untill you close the Sim and start it again.
Figured it out… it didn’t unzip properly and some files were missing.
