Failed to load database information. crdb_jdbc.dll could not be loaded

[ADRuegg]

I'm very new to Crystal Reportsm MS Visual Studio and much of the PC world (old unix programmer).
I'm trying to run an existing Crystal Report, with parameters, using Visual Studio. The database is JDBC. I made a new project J# using the Crystal Reports Application template.
package CrystalReportsApplication6;

import System.Collections.Generic.*;
import System.Windows.Forms.*;

public class Program
{
public static void main(String[] args)
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}
}

I get the error from the Crystal Report Windows Forms Viewer:
Failed to load database information.
Details: The database DLL 'crdb_jdbc.dll' could not be loaded.

I've registered this DLL, but I still get the error. Am I missing something?
