July 10, 20169 yr I have a GTX 970 with up-to-date drivers. Well Maddog any news? If Not and regarding DirectX and just to settle my Curiosity would you be willing to do a full Nvidia Driver Uninstall and then Reinstall your drivers again? Use something like Display Driver Uninstaller
July 11, 20169 yr Author Not really any news. I hadn't heard anything since DTG first said they were passing my case onto the developers, so I emailed them last week to check on the status. They assured me the problem is being looked into. However, it's been almost 2 weeks since they said they were looking into it with no communication, so I'm not feeling real hopeful. When I get some time free, I'll definitely try your idea of an Nvidia driver reinstall. Can't hurt... Thanks for continuing to try to come up with ideas...
August 7, 20169 yr Author Finally got it solved, thanks to the help of Dovetail support! They had me run Dependency Walker on the api.dll file in the FSX folder, which pointed to a problem with one of the directx10 dll files (by the way, you need to run the version of Dependency Walker that matches the application, not your operating system. So use the 32 bit version for FSX). Dependency Walker indicated that the corrupt file was in my windows/system32 folder, but 32 bit dlls in a 64 bit OS are actually in the wow64 folder. So after I deleted the offending file in the wow64 folder, reran the June 2010 DirectX redistributal, the error is gone and FSX is back in action! Note that simply rerunning the redist was not enough, I had to delete the bad file first. Thanks to everybody that helped, especially Dovetail support! Hopefully if anyone runs into similar problems they will find this thread and can get things straightened out a little more easily than I did!
August 7, 20169 yr Great to hear you got a solution! This thread had turned into an Epic head-scratching session.

November 21, 20178 yr I'm sorry, but explain just how you was able to solve this problem; I find myself with the same problem and you never mention the file you've deleted from the wow64 folder. There isn't an api.dll in the wow64 folder; it only exists in the FSX within steam. I performed nearly everything you've done until that last post, (because it was so vague) and FSX will still will not start. What file did you delete? Rodney E. Jacobs

January 6, 20188 yr Hi i just had the same problem and just managed to fix it. all i did was: 1) Go on uninstall or change a program 2) If you have SP 1 and SP 2 uninstall those 3) start fight simulator x and it will ask you for activation put in the activation and it should work just fine :)
