A document processed by the JRC engine cannot be opened in the C++ stack

Question

I have created a crystal report in vs2010 with .net4.0. when I publish the website it throws the error "A document processed by the JRC engine cannot be opened in C++ stack". I published the website in server and I'm trying to access it from client, I did keet the .rpt file in app_code, but again getting the same error. So I created a folder wwwroot and in that folder I kept the asp_client and website folder and I gave the physical path to wwwroot. everything working fine except crystal report. In .cs file code is as follows:

    ReportDocument rptDoc = new ReportDocument();
    DataSetForCrystalReport ds = new DataSetForCrystalReport();
    DataSetForCrystalReport dsHeader = new DataSetForCrystalReport();
    DataTable dt = new DataTable();
    DataTable dtHeader = new DataTable();
    dt.TableName = "dtBill";
    string ReceiptNo = Request.QueryString["ReceiptNo"];
    dt = getAllOrders(ReceiptNo).Tables[0];
    dtHeader = TblcompanysettingsService.GetOrganizationDetails();
    ds.Tables[1].Merge(dt);
    ds.Tables[2].Merge(dtHeader);
    rptDoc.Load(Server.MapPath("crBill.rpt"));
    rptDoc.SetDataSource(ds);
    CrystalReportViewer1.ReportSource = rptDoc;

stack trace of error:

[COMException (0x80041811): Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack.]

Check your path to the .rpt file! The error description has nothing to do with its real reason. It just cannot find your .rpt file!

In my case the path had to be for a .rpt file sitting in Reports subfolder:

Server.MapPath("~/Reports/InvoiceRegular.rpt");

Worked for me.
