Out of the blue I’ve begun having an issue with Toad for Oracle where it will crash silently (no dialog) upon trying to start the application. The only way I know it has crashed is by reviewing the entry in the Application Event Viewer, the most recent of which is below:
Faulting application name: Toad.exe, version: 126.96.36.199, time stamp: 0x56145048
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

Faulting application start time: 0x01d17300627214c2

Faulting module path: unknown
Report Id: a155716f-def3-11e5-ac08-340286d2b76a
Unfortunately that doesn’t tell me anything.
I did find the crash dump file and was able to examine it in Visual Studio, and this does give a bit more information:
Dump File: Toad.exe.1624.dmp : C:\Users\nb\AppData\Local\CrashDumps\Toad.exe.1624.dmp

Ok, great. Here’s the problem though - Toad was working just fine last week on Monday and Tuesday, and I haven’t rebooted or applied any software updates since then, so why is it suddenly encountering this problem?
I’ve tried completely uninstalling and reinstalling Toad and I still get the same crash behavior, so I’m not sure what to do at this point.
