Without Crystal Report on SAP Form yet

Question

Hi experts!
I follow this thread http://scn.sap.com/thread/3500063 I wonder if someone has solved this issue I've tried many different ways without success.
Summarizing: When you try to assign a report document or a CRAXDDRT Report to a crystal report viewer on a SAP B1 form like is showed below you get an exception "Specified cast not available"
   ' on Next line exception raised "Specified cast not available"
            RepViewer.ReportSource = cryRpt
I also tryed to create a crystal decisions windows form crystal report viewer, get the report source an assign it to the report viewer but I get the same error (oRpt is a report document which is loaded previously)
     Dim oCRForm As New CrystalDecisions.Windows.Forms.CrystalReportViewer
     oCRForm.ReportSource = oRpt
     RepViewer.ReportSource = oCRForm.ReportSource
If I set the path directly I get the same error
     Dim sRptPath As String
     sRptPath = Windows.Forms.Application.StartupPath() + "\Report.rpt"
     RepViewer.ReportSource = sRptPath
I'm using CrystalActiveXReportViewerLib14.CrystalActiveXReportViewer, VS2010, VB, Windows 8 Pro
Is there another way to show it on a SAP B1 form ?
Best regards.

Wow. You're mixing a number of technologies and terms, none of which really make much sense:
1) CRXDDRT is not used in an .NET apps anymore and you would not be licensed to use it anyhow.
2) You are not licensed to use the CrystalActiveXReportViewerLib14.CrystalActiveXReportViewer.
3) You are using the Crystal Reports Assemblies for .NET (not craxddrt...).
4) You  are using Crystal Reports for B1.
To use CR in a .NET application, you must use the CR viewer for .NET. Any additional queries should be posted to the SAP B1 forum:
