Hi Team,

I am trying to view report using Crystal Report Viewer version 10 in asp.net c# after i hosted my web application in server.

am getting following error event though i added the dll files in bin folder.

Coding:

//added name spaces
string pdfPath;
string pdfpath = Server.MapPath("\\KSADSRWeb\\Reports\\");
pdfPath = pdfpath + "OverAll" + ".pdf";
DataTable TargetReport = new DataTable();
string date = txtCalander.Text.ToString();
string appPath = HttpContext.Current.Request.ApplicationPath;
ReportDocument crystalReport = new ReportDocument(); //throwing below error. 
crystalReport.Load(Server.MapPath("/DemoKSADSRweb/TargetReport.rpt"));
TargetReport = GetTarget("usp_Targetvsachivement_Modified", date);
crystalReport.SetDataSource(TargetReport);
CrystalReportViewerTraget.ReportSource = crystalReport;

Issue:

System.TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. ---> System.IO.FileNotFoundException: Retrieving the COM class factory for component with CLSID {5FF57840-5172-4482-9CA3-541C7878AE0F} failed due to the following error: 8007007e The specified module could not be found.
