CTD: ucrtbase.dll based error on V5.1 [SOLVED]

Featured Replies

I have the latest updates for Windows installed, with all the Visual C++ redistributables installed. The CTDs occur shortly after take-off everytime, tested with the PMDG 737.

Problem Solved.

For anyone else facing similar issues, add the following line in your Prepar3d.cfg file, underneath [SIM], add:  AdaptiveSimGroupEnable=False

Wow. Good timing. I was just about to start a post. Off to try a flight to see if that fixed it. I haven't been able to taxi to the runway in the NGXu without P3D crashing. 

Copy and paste this into a Powershell window (I think it needs be run as admin) if you've had a crash. If nothing happens when you run it, you have not had a crash for this problem,

You guys sure this is a fix?

I just got the same ctd and i had this in the cfg.

Mike

I got to ask.  Why don't the beta testers check these things with 5.1

Activesky, sode,  pmdg, are all in the top 10 addons id say. 

I get they can't beta test everything, but surely these 3.  Whats the point of beta testing if they don't bother checking addons. Like is blantently clear here..

I was getting the crash within minutes of every take off, I added the line of code to my config file and no more crashes so far. I wonder if there isn’t more than one thing going on here, your experience implies there is.

 I got ucrtbase.dll CTD when I remove something from USB Port (Joystick or something else)

  • 1 month later...

Please help. I keep getting this crash even though I have the AdaptiveSimGroupDisable=False fix. The ucrtbase.dll crash keeps happening even if the AI traffic is turned off and only seems to happen in the FsLabs A319

Same here but with all the FSLabs planes.

Unfortunately this ucrtbase.dll error can have lot´s of reasons. If you google it, you will find multiple pages with this error mentioned.

I had the issue also a while ago and the following did help me (same message sometimes solved with different solutions as the cause was different too):

  • Reinstall P3D Client and rebuild P3D.CFG
  • Reinstall P3D Content and P3D Client and rebuild P3D.CFG
  • Reinstall Visual Studio
  • Reinstall VCRedist (C##) x86 and x64 versions from all available years you can get via Microsoft.com. Addons can also have directories with VCRedist.EXE saved....repair or even reinstall them completely
  • Unplug all USB devices. Restart PC and plug them in one by one
  • Reinstall ASP3D (completely uninstall ALL components - some uninstall questions during uninstall I decided to answer all of them with "uninstall")

ucrtbase.dll must not be an P3D related error, as you can see. Often lot´s of other PC software components can call this error.

Good luck!

Why is Visual Studio required?
