我目前正在使用visual studio 2010和MS access DB。我安装了水晶报告2008.我使用Windows窗体和水晶报告查看器控件。在按钮上单击我想在水晶报表查看器中显示数据库中的报表。但我遇到以下错误消息。

无法加载数据库信息。 
详细信息：无法加载数据库连接器crdb_p2bbnd.dll。可能未安装此数据库类型的数据库客户端的正确版本。

这里是代码

 OleDbConnection cnn; 
 DataTable OledbDt = new DataTable（数据库中的表名）; 
 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）; 
尝试
 {
 cnn.Open（）; 
 OleDbAdapter = new OleDbDataAdapter（sql，cnn）; 
 OleDbAdapter.Fill（OledbDt）; 
 ReportDocument rptDoc = new ReportDocument（）; 
我的rpt文件名abc = new我的rpt文件名（）; 
 abc.SetDataSource（OledbDt）; 
 crystalReportViewer2.ReportSource = abc; 
 crystalReportViewer2.RefreshReport（）; 
 OleDbAdapter.Dispose（）; 
 cnn.Close（）; 
} 
 catch（Exception ex）
 {
 MessageBox.Show（ex.Message，Error）; 
} 
 
}
