5.1 CTD after short flight time.

[Snowfalcon]

5.1 loaded into the sim fine.

After take off and a short flight sim freezes sound keeps going followed by a CTD. Happened with both the default F-35 and a Carenado C337. Happened about the same time and got the same issue 5 times in a row. FPS above 50 at all times. All drivers are current. No warning or code displayed. What can I post to help source this error?

@ Snowfalcon ,

I have only tested very short test flights and no problems.

What was your test flight in the F35A and I will give it a try?

For payware I also only have the PMDG737NGXu installed.

Otherwise a default P3Dv5.1 install with FSUIPC6.

By short flight I meant it CTD after about 3 min. Rolled back to 5.0 HF2 and all is good.

Hello ,

I have the same problem with P3DV5.1. I get CTD after a few minutes, independing where and with what kind of aircraft I am flying. My protocoll tells me, that the fault is in ucrtbase.dll.

I use win10, all drivers up to date, updated VC_redist.x64 drivers, I am using NVidia 1070 with newest drivers.

Please help. Thank you.

Kind regards
Michael

@ Kiel1957 ,

Is your problem repeatable?
Does it happen when you test with default P3D aircraft?

[Kiel1957]

Yes it is repeatable. I find this issue wth the F35 and also other aircrafts. It happens all the time when I try to use V5.1.

Thank you.

@Snowfalcon and Michael,

What does Windows Event Viewer say is the "Failing module" at the time of the CTD?

Same problem here. Did 10 test flights with payware and default aircraft. After 5 minutes in the air over KSEA I am having a CTD without any notification. How can I revert back to the previous version? Unfortanately I don't have the HF2 install client anymore...

Pilots reporting this problem:

Are you re-booting the PC between each flight, using default P3D aircraft in your test?

[Kiel1957]

Yes Sir, I do reboots all the time here. I try google but can't get any usable hints.

It's CTD without any messages. Only I can find are the information in the event viewer sent some minutes ago.

Kind regards
Michael

Sorry didn't answer your question completely:

Yes I am using P3D standard F35. But is happens the PMDG 737 NGXU as well. But I always test the original aircrafts first to avoid failures by the ad - ons.

Thanx
Michael

Michael,

The "ucrtbase.dll" error is what you have to chase down, in your case.

Jorgen

[Kiel1957]

Jorgen,

I will roll back to V5.0. There I didn't have the failure. I have no clou how to chase down my problem with the ucrtbase.dll. Do you have an idea what I may have to do?

Thank you
Michael
