I don't know anything about your Sage setup, but assuming the database is on a network, then yes, you need to use an ODBC Datasource manager to set up your data source that will connect your Sage client software to the Sage database. IN the 'Search the web and Windows' box, type odbc and you should be given a list of choices, one of which will be a 32bit manager and another for a 64bit manager.
Hope that helps.
