I have the v2.7 installed in FSX, FSX-SE, P3Dv2. and P3Dv3.

On checking it out, it's not working for me in FSX, FSX-SE, or P3Dv3 (all in Windows 7).

NOTE. I can't check it in P3Dv2 as I need to uninstall it, then reinstall it to re-activate it on my upgraded computer. Seeing as I'm going to buy a new Graphics Card (a 6GB GTX 1060) later this month, I'm holding off on the reinstall until after that.

Windows 10 won't activate either, so I'm planning on sorting all of that out after I install the new Graphics Card too.
