Start at the Spreadsheet_Excel_Reader::read call shown in the report and verify whether IWMPSmsData_ReportingDistictReport.xls is present and readable in the process's working directory. Reproduce the reported error with that filename, then determine what prevents reading it; done means the cause is identified and the reader handles the file or reports a useful failure.
