Hello, here the problem:
PC upgraded to Win7, reinstalled ADE9, when I open an airport, click on connect but the aircraft doesn't show up and I can't move it.
All it's fine with AFCAD and here below, my ADE Environent checker. (I don't have FSX)
Probably not related... but you never know. I see that it's looking in C:\FS9 for your install instead of the more traditional C:\program files\microsoft games\fs9 structure.
It's showing that it's seeing FSUIPC.. so that connection seems to be working.
Have you tried turning it off and turning it back on again?
I'll check my widgets and checkmarks when I get home to make sure they all line up. I'm running ADE9 in Win7 without problems.
