FileNotFoundException occured while assign DataSource in CrystalReport

问题

System.IO.FileNotFoundException execption thrown while assigning data source in report. I am using visual studio 2013, C# 4.5, WinForm application. I have installed crystal report for visual studio 13.

This is code

    DataSet ds = new DataSet();
    ds.Tables.Add(new DataTable("administration_CashDeskManager_Reports_ReportDataBusinessObject"));
    ds.Tables.Add(new DataTable("administration_CashDeskManager_Reports_ReportDataDetailBusinessObject"));

    Reports.CrystalReport.rptCashDeskTransactionLog Report = new Reports.CrystalReport.rptCashDeskTransactionLog();
    Report.SetDataSource(ds);
    crViewer.ReportSource = Report;

Error thrown on Report.SetDataSource(ds) command.

I think this error is version specific error.

Exception detail :

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

Additional information: Could not load file or assembly 'file:///C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.
