I downloaded the installer from SimMarket and executed it. It did not ask where to install the aircraft, the folder indicated on the installer is too short so I cannot determine where it is. And I cannot find a place to tell the installer where I want it to go.
This sounds like something Just Flight or Just Trains support could help with. There are links on their websites www.justflight.com and www.justtrains.net
