---------------------------
Crystal Reports Viewer

Failed to load database information.
Details: The database connector 'crdb_p2bbnd.dll' could not be loaded. The correct version of the database client for this database type might not be installed.


here is the code

string connetionString = null;
           OleDbConnection cnn;
           DataTable OledbDt = new DataTable("Table Name from the database");
           OleDbDataAdapter OleDbAdapter = new OleDbDataAdapter();
           string sql = null;
           connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=XXXXX.mdb;";
           sql = "select * from Table name from the database";
           cnn = new OleDbConnection(connetionString);
           try
           {
               cnn.Open();
               OleDbAdapter = new OleDbDataAdapter(sql,cnn);
               OleDbAdapter.Fill(OledbDt);
               ReportDocument rptDoc = new ReportDocument();
               my rpt file name abc = new my rpt file name();
               abc.SetDataSource(OledbDt);
               crystalReportViewer2.ReportSource = abc;
               crystalReportViewer2.RefreshReport();
               OleDbAdapter.Dispose();
               cnn.Close();
           }

Add the <startup> code below code under the <configuration> element in your app.config

<startup useLegacyV2RuntimeActivationPolicy="true"></startup>
   
I once encountered this error on my Windows 7 machine and it was resolved after I installed .Net Framework 4.5 on the machine.

Somehow I don't think that would have worked back in July 2014
