It's a Trust bug in SimConnect, but it is recoverable. Please see the FAQ thread FSX fails to run after FSUIPC4 first installed

Hi Pete.

For your knowledge i try to reload FSX for about 20 times and it didn't work. So i uninstalled the SP2 package and install it again,

after that it work ok, i don't know if its a coincidense.

thank's

Abi.

Yes, I think it must be. The problem is actually very variable. It is time critical -- one event occurring at the same time as another. Probably you just altered the timings by doing that. Other ways include rearranging the order of things loaded in the DLL.XML file.

Microsoft's FS team did know about this, but it involved bits of Windows as well as SimConnect and it was never resolved before the team was dispersed. To be fair to them, it has always been very rare in occurrence. I've never managed to get it to happen on any of many different systems over the years, and this applies to probably more than 99.9% of users. But for those it happens to it can be persistent until something, who knows what, changes.

Looks like im having a similar problem with FSUIPC 4.742. I get the same error message on start up of FSX and I click Yes to run the 3rd party software. Once I click yes FSX stops responding. When i check to see what the problem was before closing the problem the error is "AppHang1" Ive read your other posts and have tried being patient and starting and closing and restarting FSX for the past hour. I even uninstalled FSX acceleration and reinstalled it in the hopes the timing would be changed and allow fsuipc to work. Unfortunately there has been no change since re installing FSX acceleration. I still get the error message about 3rd party software and when i click yes to run it FSX stops responding. Please Help.

I've not heard of that one. Is there an FSUIPC4 log file produced? If so paste it here. Have you followed all of the hints in the FAQ subforum thread about this SimConnect problem?

That's generally a bad idea as it can result in SimConnect corruption.

Timing can be changed in other ways. most notably there's an FSUIPC4.INI file parameter now which can be used to delay the SimConnect opening. But this only helps when FSUIPC is actually loaded -- most of the trust bug crashes occur before FSUIPC is even started. If that's happening then there won't be a LOG or an INI file produced.

The delay parameter is described in item 40 of the recent changes list, here:

40. The order of initialisation actions in FSUIPC4 has been changed substantially in an attempt to try to avert the possibility of causing a loading problem with SimConnect, whether or not this is caused by Trust checking timing bugs. Furthermore, in order to allow changes to the timing to be tried, to avoid clashes with other competing simConnect clients being loaded at the same time, a new parameter is added to the FSUIPC4.INI [General] section:

InitDelay=0

This can be set to a value from 0 to 120 to delay the actual linking to SimConnect by that number of seconds. Whether this may help or not is unknown at this time.

If you can paste your DLL.XML and EXE.XML (if the latter exists) here then maybe I can suggest ways of temporarily rearranging the way things are loaded. You find those in the same folder as your FSX.CFG file. If you don't know where that is, check through the FSUIPC Install log and it wil tell you.
