I am facing “A call to Microsoft.Dynamics.Nav.OpenXml.Spreadsheet.WorkbookReader.Open failed with this message: foldername…” while opening the excel by using “Excel Buffer” in Function “SelectSheetsName” in “XlWrkBkReader.Open(FileName);”.
when I was tried it on App server it’s working fine, but when end user tried then system show’s above error.
“Windows Event Viewer” is also not any information.
