The report is working properly in XP But it is only showing error in Windows 7 (32 bit OS) The error info: External component has thrown an exception. System.Windows.Forms at System.Windows.Forms.UnsafeNativeMethods.PrintDlgEx(PRINTDLGEX lppdex) at System.Windows.Forms.PrintDialog.ShowPrintDialog(IntPtr hwndOwner PRINTDLGEX data) at System.Windows.Forms.PrintDialog.RunDialog(IntPtr hwndOwner) at System.Windows.Forms.CommonDialog.ShowDialog(IWin32Window owner) at System.Windows.Forms.CommonDialog.ShowDialog() at DataDynamics.ActiveReports.Document.Document.Print(Boolean showPrintDialog Boolean showPrintProgressDialog Boolean usePrintingThread) at Aoniken.CaldenOil.Windows.Reporting.ReportHelper.ShowReport(ActiveReport rpt)

If it is not the printer then you need to look at the message to see if it identifies what the external component is.

It looks like your printer is not setup right on your Windows 7 machine. Check the printer make sure it is working and printing.
