To check what version of the ODBC Driver Manager is installed in your system, you must locate the file ODBC32.DLL (usually in the system or system32 directory of your Windows installation). Click on the file with the right button of your mouse and select Properties from the pop-up menu.
This will show a window with several tabs. Select the tab labeled Version. f90SQL will work with your current ODBC Driver Manager if its version is 3.50 or higher.
