Using FME Form 2025.1.3.2 (20251029 - Build 25646 - WIN64), when using MDB_ADO database connections, either in a Reader, Writer, or a FeatureReader, FME crashes at the end of it’s process. The log screen says
Translation was SUCCESSFUL
FME Session Duration: 2.7 seconds. (CPU: 1.3s user, 0.4s system)
END - ProcessID: 9984, peak process memory usage: 89716 kB, current process memory usage: 88552 kB
so the translation is actually finished it seems, but the underlying fme.exe process crashes and never returns. So the UI never changes the red square Stop Translation button into the green triangle Run Traslation, and the Data Explorer is not started. In the Task Manager a Crashpad.exe can be seen, along with an FME Objects Worker.
This only happens if there is an MDB_ADO connection in use. Other workspaces using all sorts of Readers/Writers run fine without any issues. It seems to have started about a week ago, before that this worked fine.
Does anybody have any idea if there have been any Windows Updates that might have broken this?
