  • Using the PrintOutputController to print a report works if the application is compiled as 32 bit
  • The application compiled as 64 bit results in the following error:

System.Runtime.InteropServices.COMException (0x80040154): Class not

  • Visual Studio 2010

Reproducing the Issue

  • Create a new win app in VS 2010 using Crystal Reports for Visual Studio 2010
  • Use the following code to print a report to a printer:
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.ReportDefModel;
CrystalDecisions.CrystalReports.Engine.ReportDocument rd =
new CrystalDecisions.CrystalReports.Engine.ReportDocument();
//ReportDocument rd = new ReportDocument();
 ISCDReportClientDocument rcd;
  PrintOutputController poc;
  PrintReportOptions po = new PrintReportOptions();
  rcd = rd.ReportClientDocument;
  poc = rcd.PrintOutputController;
  po.PrinterName = "Microsoft XPS Document Writer";
  po.PrinterDuplex =
  po.NumberOfCopies = 1;



  • This is a limitation of the 64 bit builds and SDK for visual Studio .NET
  • The PrintOutputController has a dependency on the PrintControll dll
  • It is not possible to make this control 64 bit compatible due to limitations in IE 64, framework dependencies and other


  • Work-around; use the PrintToPrinter API
