Understand crashed — how do I report it?

Getting the crash details to SciTools is the fastest path to a fix. What happens automatically depends on your platform.

Windows — automatic error reporting

On Windows, an unhandled crash triggers the built-in reporter, which shows a “SciTools Support” dialog with Send and Send With Dump File buttons. Whether it prompts is controlled by Help → Privacy (the Privacy & Error Reporting page): report automatically, ask each time, or never.

Behind the scenes it writes:

  • A crash log appended to %APPDATA%\SciTools\<app>.log — includes OS, build number, message, workfile, exception code, loaded modules, and the stack.
  • A minidump under %TEMP%\SciTools\ named <app>-<build>-<YYYYMMDD>-<HHMMSS>-<pid>-<tid>.dmp.

Choosing Send With Dump File uploads both, which gives support the most to work with.

macOS / Linux — send the details manually

No automatic crash upload on macOS or Linux

The automatic reporter is Windows-only. On macOS and Linux, Understand does not capture or upload a crash automatically. Email the details to [email protected] — include your Understand version/build, your OS version, and what you were doing when it crashed. If your OS produced a core/crash file, attach it.

Always helpful: your build number and analysis log

  • Build number: Help → About Understand.
  • Analysis log: Help → Send Analysis Log… opens a pre-addressed email to [email protected] (this is the analysis log, not the crash log — send it when the problem is bad/incomplete analysis rather than a hard crash).
