ODBC driver in Windows 7 64bit

If you are working with W7 64bit, and go to

Control Panel  -> Administrative tools,-> Data Sources (ODBC)
The ODBC Data Source Administator Window will pop up.
This is actually pointing to this .exe file "C:\Windows\System32\odbcad32.exe"

 If you try to Add a new ODBC data source

only the SQL Server driver will show up.

To sort this problem you need to load up the 32bit version of this Window that can be found at the following path.

C:\Windows\SysWOW64\odbcad32.exe

 This way you can create DSN connection other than SQL Server on a 64bit OS.
