FSX crashes rarely have one universal cause. This hub separates menu failures linked to UIAutomationCore.dll from 32-bit out-of-memory limits, black screens, graphics driver problems and freezes when loading or editing flight plans. It explains what each symptom suggests before you start replacing files or removing add-ons.
The troubleshooting answers use repeatable checks: testing a clean configuration, isolating scenery, aircraft and utilities, reviewing Windows event details, and reducing memory-heavy settings where appropriate. They are written and tested by the Fly Away team for both boxed FSX and Steam Edition, with care around legacy DLL fixes and version-specific behaviour so a speculative cure does not create another fault.
