You need only install the ODBC driver for your DBMS once, and you can use it with more than one data source. If you choose the Typical setup option, Setup provides MFC Database Support and installs the ODBC drivers for Access, dBase, FoxPro, and SQL Server automatically. You can install the additional drivers provided with Visual C++ (Text, Paradox, Excel, and Oracle) by running Setup again, as described in the following procedure.
If you want to install other drivers not shipped with Visual C++, refer to the documentation that came with your driver. You can also review the ODBC SDK documentation, in particular, the Installing Drivers topic.

If you do not want to install DAO database support, clear the Microsoft Data Access Objects check box.
