Since I upgraded to Window 11, I have been unable to run FSX-SE. Normally, FSX-SE starts from Steam. I can start Steam, but FSX fails from there. Message: "The application was unable to start correctly - error code 0xc0150004." I tried reinstalling Steam and FSX, verifying the files, creating a shortcut from the Steam-FSX directory, and running as administrator, but no luck there. From Steam, I can run other applications, such as FS-4 and War Thunder. I can run MSFS ok, but I can't run X-plane.
Other things I tried: "Run programs made for previous versions of Windows," and Program Compatibility Troubleshooter. Tried to run through GeForce Experience, but same results. I saw a website that claimed FSX needs DirectX 11. I couldn't find a way to revert. The version I have now is DirectX 12 Ultimate. I installed Microsoft Visual C++ 2005 Redistributable (x64). Downloaded and installed FSUIPC-4. All to no avail.
I hope someone reads this and helps me solve this issue.
Thanks,
Gerry
