    Rather embarrasing for me. A neighbour wanted me to install a flight simulator on his wife's laptop running Windows 7 with DirectX 11.
    He currently has it installed on Windows XP with DirectX 9.0c. After installing from cd to the Windows 7 laptop, the program refused to launch as it was looking for a DirectX 9.0c .dll
    I then installed DirectX 9.0c but dxdiag still shows DirectX 11, and needless to say the program still wouldn't launch.
    I assume the program will not work with anything but DirectX 9.0c but always thought that that there was backwards compatibility ?
    The following from their website support page:-

    So, is there no way to get the thing to work on Windows7 ?

    Did you try to run it in compatibility mode for XP? It may not help but couldn't hurt. What kind of graphics adapter does this laptop have?

    Thanks, I forgot all about compatibility mode. Will give it a try. Graphics is Intel integated HD, as far as I recall. It runs on the XP desktop without 3D, but of course topographical and other features are not available.

    Might be the problem. :p

    Anyway, did you install the June 2010 Redist? Might try it if you haven't:

    Not sure if this helps, but...
