Hello everyone,

I have been using FSX on and off for the past five years or so. I remember playing it on Windows 7 and Windows 8 with little to no problems. Out of nostalgia, I decided to start the game up once again after a long period of not playing, this time on my new laptop, which has Windows 10 installed.

And the constant crashes have been driving me insane. 

It's really bad. It has gotten to a point where I can't even finish a single flight without the game freezing for a few seconds and then giving me the ol' "a fatal error has occured" message. It happens at random points during the flight -- for example, last night it crashed on me while I was landing at O'Hare after flying from JFK, and this morning it crashed before I even took off from Prague airport. However, every single time the game crashed, it was after I tried using the menu (the one that appears when you right click in flight).

I tried everything I could think of to fix it -- I ran it in multiple compatibility modes, inserted UIautomationcore.dll into my game folder, updated all of my drivers... but to no avail. I'm getting really desperate at this point.

Here's the error message that appears in Event viewer in Administrative tools:

Faulting application name: fsx.exe, version: 10.0.61355.0, time stamp: 0x4643ee0a
Faulting module name: uiautomationcore.dll, verze: 6.0.5840.16386, time stam: 0x45398e5f

And before you suggest it -- I already tried putting the second version of the .dll into my folder. That just gives me the same error, only the second line of the error code is different, reading "unknown" instead of "uiautomationcore.dll" and all of the subsequent numbers as zeros.

Thanks for the help!

You need to install Acceleration or FSX SP2 - https://www.microsoft.com/en-us/download/details.aspx?id=8986.  The version reported in your Event Viewer is FSX SP1.

Best regards,

Alright, thanks! I'll see if that does the trick.

If you are going to reinstall Acceleration, then I'd pay the $5 and get the FSX Steam Version. It's Acceleration with some important updates (that also aid with compatibility).

I've run all versions of FSX, and the Steam version is by far the best and most stable.  Note that there may be a few addons not compatible with FSX:SE (though I'm not aware of a single one), so double check this before deciding to go that direction.

Best wishes.

 

 

Installing SP2 didn't really help, my game still crashed. About 5 minutes after taking off, I wanted to take a closer look at the aircraft flying directly in front of me, so I went to select the "Airtraffic" option in the menu and bam -- freeze, followed by a fatal error message.

The error code is a little more interesting now, though.

Faulting application name: fsx.exe, version: 10.0.61472.0, time stamp: 0x475e17d3

What should I do? Should I go ahead and install Acceleration now?

You can install Acceleration or you can install SP2 but not both.  If you do install Acceleration, you must uninstall SP2.

If you have Windows 10 you must have a version of the uiautomationcore.dll in your main FSX folder (see page 27, AVSIM CTD Guide).

Best regards,

Jim
