Hi,

While executing the report “Print to Excel” ticked as true and getting error as shown below,
A call to Microsoft.Dynamics.Nav.OpenXML.Spreadsheet.WorkbookWriter.create failed with this message: The document type is invalid. Verify the file extension.

I Already installed the “Open XML SDK 2.5 for Microsoft Office” which is available in NAV2016 product. I used NAV 2016 CU10 product for this. “Excel Add-in” installation also done in my computer.

suggest me the solution.

Regards,

Baba Guru.
