I cannot get the program from Steam that controls in inventory of what I have installed. This is a new computer and does not have my copy of X-Plane. When I try to download the Steam program it treats it as a text file and not a program. It wants me to indicate what program will run it (from what format or program?). I really want to play and learn from the X-Plane again and have loved it so far. Just need it loaded on my new machine which will be much better. Thanks!
