Wrong Local header signature: 0xE011CFD0 in NPOI (NPOI forms closed unfortunally) RRS feed

  • Question

  • Hi,

    I get the following error message from NPOI:

    Wrong Local header signature: 0xE011CFD0

    This message comes from a secured sheet in Excel. If I enable editing then it will work. It is the problem that it works under excel 2010 and not under excel 2007 and open office. There I get the error message. It happens while I want to open the xlsx. In csharplib.zip makes the exception.
    I can not find NPOI forums or are locked. Maybe someone can help you?

    Greetings from Amsterdam the Netherlands
