FSX keeps closing by itself

[TopCat747]

I recently installed some AI aircraft from World of AI. It seems to run perfectly fine with no lag. However, at random times it seems to automatically close FSX for no reason.
I have just installed FSX about one hour ago and runs fine.

Any idea why? - This happened when I was about to take off on one flight, and then on another flight, I done a go-around and then it automatically went off.

Any assistance would be extremely appreciated.

I had a similar problem once when in multiplayer mode and someone joined the same session joined with an aircraft the same as one I had installed which had a corrupt gauge file. I only found this by removing each gauge one by one until the problem went away.
So maybe one of the associated files for your AI aircraft is corrupt.

Thanks but it didn't work. I deleted the UiAutoMation.dll in Sys32 and SysWOW64 and replaced a new one in my FSX folder. It worked.
