I just installed the latest ASPOSE version and it dies on this statement now…
excel.Open(path + “scheduleTemplate.xls”);
Parameter name: startIndex) —> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: startIndex
at Aspose.Excel.as.a(MemoryStream A_0)
at Aspose.Excel.as.a(String A_0)
at Aspose.Excel.Excel.Open(String designerSpreadsheet)
I can email my template file if that would be helpful.
