GSX CTD on Windows 10 after latest update

[Guggibob]

Hello guys,

serious issue with my FSX. After updating to latest version of GSX my FSX has a CTD short while after the airport has loaded. It happens at all airports with the PMDG 737NGX. I haven't tried other airplanes yet.
What could be the reason and what could be a lucky solution for this issue? Error message are the following:

I copied uiautomationcore.dll from Windows10/system32 to fsx with and without registration, but this didn't solve problems.

My configuration is
OS Windows 10
FSX Gold Addition with ACC Pack installed.
PMDG 737 NGX
Active Sky Next
REX Textures
FSPassengers
German Airports 2 and 3, FSX Balearen and some other sceneries
FTX Global
FS Global 2010
UT Europe
Ultimate Traffic 2

Kindly Regards

The uiautomationcore.dll error message is something that goes back to Windows Vista, and it hasn't been entirely fixed. Or, more precisely, there's not clear and definitive answer which version is the safest to use, since there are many of them out there, and some user found a version is more stable than another one, but it's not always the same.

I think in this case, the uiautomationcore.dll MADE FSX crashing, which made Couatl.exe crashing too.

In any case, be sure you reinstall GSX with the antivirus TURNED OFF, and configure it to exclude the whole FSX folder from scanning before launching FSX after the update. This is *very* important and has fixed most of the crashes that were initially reported.
