Hi,

I have one application using UltraGridExcelExporter in Infragistics2.Excel.v10.3 to export excel file. It gives below error. 

The application works fine util I upgrade Office  2013 to Office 365. 

See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.
