problems with dsofile.dll RRS feed

  • Question

  • I'm using dsofile.dll (2.1.2841.0) to read meta information from a closed Excel workbook. It has to be done without opening the file.

    It worked fine for a long time, even with Windows 10 and Excel 2016.

    From one day to the next it stoped working with error message:

    -2147217148 - The document is not an OLE file, and does not support extended document properties.

    Maybe it has to do with file msoshext.dll ( which was updated from Microsoft on July 14th 2017.

    Does someone made the same experience or knows the solution?

    Thx Reinhard

  • He reinht,

    Does the msoshext.dll updated with Office version? I suggest you revert your office to a previous version before July 14th 2017 and then check whether the issue still exists.

    Best Regards,
