Prepar3d Pro v5.1 crashes on startup, new install, no addons

[sgoen]

Please forgive me but I am a little frustrated right now after paying over 200.00 for Prepar3d Pro. I downloaded the program and then installed light the direction said to do. Upon opening the program, the program finishes the installation and goes to a screen for weather and aircraft change. Once at the screen the program crashes. I have tried to run it in administration mode and with out. I have uninstalled, restarted the computer and reinstalled the program with the same results. At this point I don’t know what to do. I am frustrated because when I pay for a program, I expect it to work. My computer is not the problem as it it built to run programs that require a much stronger system the your program requires. Any help that you can give me would be greatly appreciated

Let me guess... you have an nVidia graphics card, and the driver version is 465.89?

If so, roll back the driver one version. This is an nVidia problem, not a P3D problem.

After rolling back the Nvidia driver by one version, the sim is now working fine.
Thanks you for overlooking my frustration.

the problem is if I go back to a previous version, then they run badly or crash other games like Iracing
