FSX or Prepar3D crashes when FSUIPC reads weather data from SimConnect

[katoema]

Hello Pete, today I have suddenly have FSX failing to load with the message "Flight Simulator has detected a problem with a third-party software program (add-on)"

Name: FSUIPC4 DLL: FS new universal IPC interface

Version: 4.974

Company Peter L. Dowson

File: Modules\FSUIPC4.dll

FSX then CTD if chosen to continue!

I have recently started to use FSXWX on a client machine, so following all your above advices, there is no change

I hold a licence for both Wide Server/Client and FSUIPC

Do you recognise this issue?

 

Thanks

 

Martin

You added this to a thread in the reference section "FAQ". I know that thread may well be relevant, but so we can deal with it as a support query i've moved it here.

Well, in that case we need the CTD details, please, from the Windows Event Viewer. Paster a copy here. It's easy to cut the details from the Event Viewer display options.

We also need to see the last FSUIPC4 Log you  got from FSUIPC. It'll be in the Modules folder.

Try with FSXWX disabled AND, before starting FSX, again deleting the wxstationlist.bin and all of the .wx files. After all, it does seem mighty suspicious that it started when you started using that program.

I had deleted the wxstationlist.bin and all of the .wx files after first reading your text in FAQ. However, I also saw that there was a slight FSUIPC4 version increase from v. 4.974 to v. 4.975a and therefore updated my version. The outcome, yesterday, is that FSX loaded with no error message.

 

Today, everything seems to be functioning correctly!

 

Can you indicate what the issue may have been?

 

Thank You

Not really, as your FSUIPC4.LOG is from a good session. The previous (last crashed) log would have been more informative.

However, from the Windows crash data it would appear that the problem was due to some corruption in memory. The first was in ATC.DLL and the second in AI_PLAYER.DLL, and assuming that it isn't a corrupt install of FSX the most likely problem was corruption due the SimConnect loading bad weather data. Maybe the FSUIPC update has caused a slightly different memory arrangement, so something more innocuous is corrupted. Or maybe your deletion of the weather files paid off this time.

Thank you, I had only registered as a member of the forum after the event of the FSUIPC update. I now appreciate the necessity for a log directly after an event. Point noted.

 

Thank you for your time indeed/
