The WBEM SDK installs the 2.x ODBC components (driver manager and administrator) if required. The 3.0 ODBC driver manager is backward-compatible with 2.x ODBC drivers.
Use the Control Panel ODBC applet to add, modify, or delete data sources from the ODBC.ini file or the registry. An implementation of ConfigDSN is provided to enable adding a data source. When creating a data source, ConfigDSN may prompt you to specify its category.
If you use the SDK Driver Setup Toolkit, you can install the adapter from the standard Control Panel ODBC applet.
You can install the ODBC software programmatically, silently or non-silently, from SMS startup or a menu option. SQLInstallODBC is called to install the ODBC software and the adapters.
