Notes Client unable to detect odbc on Windows 7 32-bit

I upgraded my pc from windows XP to Windows 7 32-bit.

When I login as Administrator in windows and open my Lotus Notes application which uses odbc to connect to mssql database, it works fine. However if I login in windows using different username (even though with Administrator access) then I open my Lotus Notes application, it cannot detect the odbc.

Is there something wrong? It seems Notes client is unable to detect the odbc in Windows 7 32-Bit if the user is not Administrator.
