  • Question

  • Good day!  I am trying to do an analysis on a 3rd party application that keeps crashing on an end user of ours.  I did an analysis and it points to an Access violation being the issue, although I can't pinpoint where or why.   Any suggestions?

  • Hi Townshend84,

    Thank you for posting here.

    For your question, the information you provided could not get what cause the crash. How do you analyze the crashing application? With dump file? Could you provide the dump file for us?

    >>*** ERROR: Symbol file could not be found.  Defaulted to export symbols for bnt.dll -

    When you analyze, have you load the symbol file?

    Best Regards,

    Wendy
