how to establish a ODBC connection in Windows 7 64 bit ?

Hello,
I have created a ODBC connection between MS Acceess 2003 and Excel 2003 in Windows 7 32bit enviroment . The Macro ( code ) is as follows :
ActiveSheet.QueryTables.Add(Connection:=Array(Array( _
"ODBC;DSN=MS Access Database;DBQ=D:\Acces7dat\STOCKS.mdb;DefaultDir=D:\Acces7dat;DriverId=25;FIL=MS Access;MaxBufferSize=2048;PageTim" _
), Array("eout=5;")), Destination:=Range("A1")) ... etc , transferring data from MS Access file stocks.mdb to an Excel spreadsheet for proccessing etc . All this works fine for the last three years until I have installed Windows 7 64 bit . Googling the problem found that I have to run the Windows/SysWOW64/obdcad32.exe file . Doing this appears the ODBC Data Source Admiinstrator with the tabs :
User DSN , System DSN , File DSN , Drivers , Tracing , Connection Pooling and About , and I can't configure all this in order to create a ODBC connection . First , is this the correct way to solve the problem and second how to setup the ODBC Data Source Admiinstrator under all these tabs ? Any help ? thanks in advance.
PS : I have reinstall Ms office 2003 in order to add missing items etc but no luck .

the problem was solved by ODBC Data Source Admiinstrator , pressing the button " Add " and afterwards writing " MS Access 2003 " just right the DSN ( = Data Source Name ) label and OK , no matter should understand all of this .

thanks anyway
