I get the error message indicated in the title each time I log off the computer after the application is closed.

The .net application uses a crystal reports active-x.

How do i get rid of this error?

opening of report:
crv.ShowCloseButton = true;
                crv.Visible = true;
                crv.BringToFront();

                crv.ReportSource = rptSecur03;

How do you close the report viewer?

How do you assign the report file to the viewer?

I used the folowing code on form_closing to clear the com object from memory

private void clearReportsFromMemory(CrystalDecisions.CrystalReports.Engine.ReportDocument rpt)
        {
            try
            {
                if(rpt != null)
                {
                    if (rpt.IsLoaded)
                    {
                        rpt.Database.Dispose();
                        rpt.Close();
                        rpt.Dispose();
                        GC.collect

                    }
                }
                   
             
            }
