In place of the 64-bit version, use the 32-bit ODBC administrator, named odbcad32.exe, which is located in the %systemroot%\SysWOW64 folder.
To use the 32-bit ODBC Data Source Administrator
Click Start on your desktop.
Click Run.
In the Open box, enter:
%systemroot%\SysWOW64\odbcad32
Click OK.
The 64-bit version of Microsoft ODBC Data Source Administrator
must be closed before you can open the 32-bit version. For example,
an attempt to execute the 32-bit version while the 64-bit version
is running causes the 64-bit version to continue processing and
prevents the 32-bit version from opening for administration.
