First of all I'd like to thank every one of you who took part in my survey.
Well, here are the results of your 99 responses:
As you can see, FSX keeps its first position as the most frequently used simulator, followed by FSX:Steam Edition and Prepar3D v3 neck and neck. Quite surprisingly, Prepar3D v1 is still being used. Honestly, I was about to remove its support in the new vLSO version, but definitely I'll have to keep it there.
As I expected, most of you have two (or perhaps more) flightsims and fly them on a regular basis, so the new vLSO version will support any number of simulators, currently up to five, installed on the same machine.
