In case anyone is having trouble getting the simulator to open once they download it, this video explains the 7 zip download and file extraction
For those wondering what kind of joysticks/rudder pedals work with the software, I have successfully used the following:
Thrustmaster Warthog Joystick, Thrustmaster T Flight Hotas X, Logitech G Pro Pedals, CH Pro pedals. I have tried both sets of pedals with both joysticks and all combinations work (The pedals and joystick run concurrently so you can do both the horizontal and vertical tracking at the same time) I think someone else was only able to get one work at a time, with a different hardware setup.
