AccessVio RRS feed

  • Question

  • AccessViolationException when we try to access the IMAPI objects. This seems to be happen in few machines after windows update (August 13, 2019—KB4512501 (OS Build 17134.950)).

    1. Also it not only affect IMAPI it affect different places where Interop Marshaling is happening.
    2. Also we found AccessViolationException in our Reporting component. (LayoutManager.UpdatePageBreaks())
    3. UCMS IT service tool also crashing because of the same issue.

    Currently we found it is happening in 4 machines after this KB update. Once we uninstall we don’t see this issue.

    Attached call stack for various places.

  • Hi gnanamu,

    Thank you for posting here.

    According to your description, your issue is more related to Windows 10 update, so I suggest you ask your question in Windows 10 forums for more help.

    The CLR Forum discuss and ask questions about .NET Framework Base Classes (BCL) such as Collections, I/O, Regigistry, Globalization, Reflection. Also discuss all the other Microsoft libraries that are built on or extend the .NET Framework, including Managed Extensibility Framework (MEF), Charting Controls, CardSpace, Windows Identity Foundation (WIF), Point of Sale (POS), Transactions.

    Thank you for your understanding.

    Best Regards,

    Xingyu Zhao
