FSX Steam Edition not loading correctly

[Will17824]

Good morning,

I'm having issues with FSX SE not loading correctly.  My computer is only a few months old and I'm running Windows 11.  I have downloaded FSUIPC4 as I need it to run ACARS applications from various Virtual Airlines.  My issue occurs when FSX SE loads.  Within about 5 seconds, it crashes.  Sometimes, it takes 3 or 4 attempts to load correctly.  Once it does, no problems.  I have flown 4 hours at times with no issues.  I have reloaded FSUIPC several times with no changes.  Once I delete FSUIPC, my sim runs fine, no startup issues.  I'm sure that I'm doing something wrong or something is not configured correctly but I am at a loss as to how to correct this.  Any help would be greatly appreciated.  I have included the event log below.

It looks like FSX crashes in the API.DLL are due to a recent windows update - please see 

and on avsim: https://www.avsim.com/forums/topic/635654-fsx-apidll-crash-no-fixes-in-other-threads/

I have also just asked the OP of these threads for a reference to the confirmation of this issue.

Hopefully this will be fixed in another  windows update.

John,

Thank you for your reply.  I will review the links that you provided.  Hopefully this will be resolved with the next update.  That seems to be about the time that I purchased my new computer.  Many thanks.

Just a quick follow-up.  I deleted FSUIPC and have flown many times without FSX SE crashing.  A few windows updates have come out, and each time, I reloaded FSUIPC and started Steam and I immediately crash upon loading.  Do you think there will be a fix any time soon or am I just out of luck?  Are all Steam users with Windows 11 having this issue?

I am not sure where the problem is, so do not know where the fix will be coming from. There is no fix for this in fsuipc4, which is closed for development and has been for several years.

I use FSX-SE on Windows 11 without issues, although i don't actually use it that often - only to investigate user support issues. I have not seen any CTDs at start-up.
