Surely you jest.
"Work all the time on all systems" is absolutely, patently, and completely absurd on it's face.
Not even "Solitaire" works on all Windows computers, all the time.
As someone who has operated the VRS Superbug since day one of the FSX release, as well as being part of the original CLOSED BETA test group, I can assure you there really is no interface whatsoever between the two products. vLSO could care less what the vendor or aircraft it handles is about.
I have also been running vLSO since November of 2011(vLSO 2 Beta) without problem, and it continues to perform flawlessly to this day (vLSO_07100).
My system is a Windows7 Professional at current maintenance levels, with ATI video, and SoundBlaster audio cards.
If it doesn't it work on your system: "IT's YOUR SYSTEM".
And, paying for it isn't going to fix the problem.
