Hello,

In supporting CR SDK's for the past 26 years I don't recall anyone trying to use a .NET and our JS files...

I don't believe it's supported, those JS files under the Viewer folder are for internal use by our Viewer and not supported by direct use.

The error is likely due the Report Engine has not be initialized in your project.

Here's a simplified use of the Engine in a WEB app:

using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml.Linq;

using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Web;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Page_Init(object sender, EventArgs e)
    {
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        rpt.Load("C:\\Reports\\Reports\\General Business\\World Sales Report.rpt", OpenReportMethod.OpenReportByTempCopy);
        CrystalReportViewer1.ReportSource = rpt;
        Response.Write("hello");

    }
}

Printing Crystal Reports in .NET

Also note you must install CR for VS using the EXE, in your case the one for VS 2019 to properly integrate into Visual Studio. The one for 64 bit is for VS 2022 since it's a 64 bit application. Also to get all of the registry keys created etc.. You cannot manually distribute the runtime, to many COM dll's to register etc.

MSI's are for redistribution only.

I am using visual basic aspx files to open the reports

Partial Class myMainAllDevices
Inherits System.Web.UI.Page

Dim myMainAllDevices As New CrystalDecisions.CrystalReports.Engine.ReportDocument

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

If Session("Report") Is Nothing Then
Report.Load(Server.MapPath("Report.rpt"))
Session("Report") = Report
Else
myMainAllDevices = CType(Session("myMainAllDevices"), CrystalDecisions.CrystalReports.Engine.ReportDocument)
End If

Report.Refresh()

Report.SetDatabaseLogon()

With CrystalReportViewer
.DisplayGroupTree = False
.DisplayToolbar = True
.EnableDatabaseLogonPrompt = False
.EnableDrillDown = True
.EnableParameterPrompt = False
.HasCrystalLogo = False

End With

End Sub
