P3D 4.2 with all simconnect installed.  Almost every time when I close P3D I get the following error message.  Anyone else has the same issue?  Thanks in advance.

This is a SimConnet conflict, try reinstalling your legacy SimConnet clients under P3D \ redist\ folder.

Install all of them except for the Japanese and Russian version.

I have this same crash. I reinstalled Simconnect as suggested by Simbol but no joy - still the same crash on exit.

What happens if you stop all the traffic before exiting by pressing shift+T?

That seemed to resolve it.

So for some reason the SimConnet.dll cannot handle the shutdown when the traffic is active on your system.

How much traffic are you using? Also do you have FSUIPC?  If so are you using the traffic limiter from this tool?

50% airline - everything else 0

Yes, paid version

Not used. Set to 0.

Thanks for your help

Ok I wonder if FSUIPC has something to do with the crash, I have UTL but not FSUIPC and I don't experience this issue.

S.

I’ll try disabling it and see what happens.

No joy - disabled FSUIPC but UTL still crashed on exit.

Well was worth a shot, anything else you have that uses SimConnet?

S.

I run the usual aircraft add-ons i.e PMDG, FSL, Realair, Active Sky, EZDok. I don't really run a myriad of other add-ons other than those.

Never mind, I am sure a fix will eventually come. It only crashes on exit, which is annoying more than anything else.

Thanks for your help - if I find a solution I'll post here.

Have you updated Ezdok to the latest?  This uses SimConnet..

Ok I haven't updated yet, I will try later this weekend to see if after doing so I can repeat the crash.
