Crystal报告：无法打开连接

我的数据库是一个远程的Mysql数据库，我'm able to access the crystal reports of my application through various PC'但是有一台PC有问题，即使我安装了mysql连接器并且创建了与我的数据库连接成功使用ODBC . 但是当我加载报告时，它会显示一条消息"Failed to open connection"

我使用以下代码进行手动连接：

cI.ServerName = "Driver={MySQL ODBC 5.3 Unicode Driver};Server=x.x.x.x;Port=3306;Option=3;";
            cI.DatabaseName = "dbName";
            cI.UserID = "username";
            cI.Password = "pass";

            foreach (IConnectionInfo info in report.DataSourceConnections)
            {
                info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password);
            }

            foreach (ReportDocument sub in report.Subreports)
            {
                foreach (IConnectionInfo info in sub.DataSourceConnections)
                {
                    info.SetConnection(cI.ServerName, cI.DatabaseName, cI.UserID, cI.Password);
                }
            }

我得到这个例外：

System.Runtime.InteropServices.COMException (0x800002F4): Failed to open the connection.
