This has probably been solved by now - but I ran into the exact same problem.
When I installed I failed to approve the fsinfo gauge prompt. The program completed
and of course no fsinfo was allowed to be displayed in the window.
I uninstalled, reinstalled and made sure this time to say OK to the gauge prompt - now it works fine.
regards.
Just realised I was talking rubbish - what I had done was to originally install the fs9 version,
after uninstalling and installing the correct fsx version everything worked fine.
Sorry for the confusion.
