FSUIPC7 7.5.3 Crashes the Sim FS2024 SU3 beta 1.5.10.0

FSUIPC7 7.5.3 Crashes FS2024 SU3 beta 1.5.10.0

• When starting with sim in EXE.xml
• When starting after sim is already running in the menu
• When starting in cockpit crashes the sim directly

It does not crash FSUIPC7

As this is in the beta, you should wait for a fix in the beta. FSUIPC7 is an external app and in no way should it crash the FS.

Maybe check the Asobo beta forums to see if anything has been reported there regarding simconnect apps.

I have had a severe crash on my development PC during a windows update and cannot look into anything at the moment until I have repaired this.

...and are you sure this is related to FSUIPC7? i.e. does it run normally without FSUIPC7 running?
There are lots of reports of CTDs in this beta version - see https://forums.flightsimulator.com/t/ctd-loading-into-1-5-10-0/727551

And I cannot investigate MSFS crashes - you need to report to Asobo.
Even if the SimConnect API has changed, it should be backwards-compatible, so I am confident, even if this issue is provoked by FSUIPC7, it is an issue for Asobo and must be fixed by them.

I know that SU3 is still in beta but I never had any problems with FSUIPC7 in any stable or beta versions.

On the official forums the problem has also started buzzing sinds the release of SU3 1.5.10 yesterday.

There is no mention of any updates in the beta that affect the SDK and SimConnect.

That's why I'm confused on to why FSUIPC7 does directly crashes the Sim when it connects in anyway with SimConnect.

No other utility that I have and uses the SDK or SimConnect crashes the Sim.

As I was a software developer for many year (Microsoft business software) I will fully respect that you can't fix this asap so please take the time to fix it.

I just wanted make you aware of this problem for future releases.

Regards Hans.

[Dutch60]

The main problems where with SU3 beta 1.5.9.0 and entering the cockpit where all official FS20 and some FS24 where crashing the Sim.

FSUIPC7 was working fine in SU3 beta 1.5.9.0

These problems are now fixed in SU3 beta 1.5.10

PCUIPC7 is the only SimConnect app (I have) that is crashing the Sim in SU3 beta 1.5.10.0.

Regards Hans.

Other SimConnect apps I use are:

• Virtual Fly HUB for my Virtual Fly controllers.
• Octavi IFR-1 for my Octavi autopilot.
• FSRealistic
• Auto-FPS
• Beyond ATC
• FlyByWire FSLTL
• ...

There is nothing wrong with FSUIPC and there is no fix, unless SimConnect is no longer backwards-compatible (which I very much doubt!). This needs to be fixed by Asobo.

This has happened on previously beta releases and is usually fixed in a subsequent beta update.

As I said, there is no way I can fix or investigate a sim CTD, only report this to Asobo.

[Dutch60]

Ok clear thanks

[John Dowson]

You could maybe try removing the FSUIPC WASM from your community folder. You won't have access to lvars or presets, but that would test if its the WASM thats the issue, not FSUIPC7 itself. There was a report/comment on that link I posted that said this fixed the issue.

• Removing FSUIPC7_WASM.wasm
• Removing events.txt and myevents.txt
• Stripping the PCUIPC7.ini file of all aircraft specific entries.

Did not fix the problem.

As I have been using FSUIPC forever I know you are a very experienced developer!

I don't know if you use C++ or C# but this is some example code where things go wrong.

These errors are due to the fact that MSFS has crashed and is no longer available.

As I keep telling you, there is nothing wrong with FSUIPC7. This needs to be fixed by Asobo.

[Dutch60]

Ok thanks for the investigation I just have to accept it's Asobo is messing things up again!

Up until now I never ran into major problems with the stable and beta version but the last two SU3 betas are a true ....show.

Kind regards Hans.

[John Noe]

All I know is everything works in 15.10.1 until I load FSUIPC then CTD without hesitation.  I don't know if it crashes by itself or through Simconnect.

[QFAussie]

I have the same experience.

The sim loads without FSUIPC. When I add FSUIPC, I get a CTD.

[Dutch60]

Good to see I'm not the only one affected by PCFUIPC crashing FS24 SU3 1.5.10.0

Let's hope Asobo can fix this a.s.a.p.

[QFAussie]

Dutch,

Although I support what you say.

I can also say that when I select anything bigger then GA, I still get CTD, without FSUIPC installed.

So I do think it is part of the problem, its not the whole problem.

[Dutch60]

I tried something bigger than GA ''A320neo from EHAM Schiphol" (no FSUIPC) and it worked just fine no crashes with settings at Ultra and at 4K.

[QFAussie]

Have you tried anything else?

I'm not a technical expert, but I think it's a simconnect issue. Once MSFS fix simconnect, FSUICP will work again.

[Dutch60]

I used to be a Microsoft business software developer and in the FSX day I wrote a small app using SimConnect and FSUIPC but that definitely does not make me an expert on developing something for SimConnect.

What aircraft or anything else that I own would you like me to see if it works in FS24 SU3 1.5.10.0?

I own the Aviator Edition and a lot of Carenado and Just Flight GA aircraft but I don't have any 3rd party big birds.

[QFAussie]

I've never developed anything, but have used every sim since MSFS95 and a whole bunch of add ons, apps, mods etc. I also own the Aviator Edition.

I've done a little more testing. All at YSSY Flytampa to stay consistent. 

I tried the new A359 ULR from Inibuilds and I re tried the A333. Both loaded in fine if I closed GSX before attempting anything.

Volenta - no crash, no tracking without FSUICP

Navigraph hub/simlink - no crash

A Pilots Life 2 - Opens but doesn't speak to the sim as it requires FSUICP

BeyondATC - The app opened, but couldn't find a connection to the PC

GSX - If allowed to auto start, causes CTD when attempting to start a flight. If GSX closed prior to starting a flight and then manually opened, GSX won't open

Active Sky - CTD

Simapp pro (winwing) - works, no crash

I then did the same with the Cessna Skycourier. When I attempted to open BeyondATC, it attempted to load into the flight and then CTD.

All I'm saying is, if CTDs are still happening, even after FSUICP is removed, I think we can rule it out and more then likely Simconnect is the issue.

 

 

 

[Dutch60]

Great testing and I totally agree that it's very likely a SimConnect is the issue.

A lot if external apps seem to result in CTD.

Let's see and wait what SU3 1.5.11.0 will bring us.

[QFAussie]

External apps seem to be the biggest issue. Xbox users on the forum seem to have little to no issues. Meanwhile us PC users are going nuts over it.

I just hope when it comes out, that FSUICP and all the other apps go back to working. 

I find it hard, that an organisation the size of MS/Asobo, didn't test this before releasing it.
