When you need to work with 32-bit ODBC drivers on a Windows 2003 64-bit environment, you may find that after installing the 32-bit drivers, you can’t see them under the ODBC Data Source Administrator.

In order to manage those 32-bit drivers, you need to launch the 32-bit ODBC Data Source Administrator.

Just click Start > Run and type the following:

%systemroot%SysWow64odbcad32.exe
