How do I move the program (and all of the forms and data) from one machine to another?

On the OLD machine, use File - Preferences in Government Forms Software (GFS) and make note of the values for both the Form Directory (Folder) AND Data Directory (Folder).  In most cases the value of these folders will be the same.   

AFTER downloading, installing and entering your FEIN and password in GFS on the NEW machine, copy all files with the following extensions contained in the folder(s) defined above to the equivalent folder(s) on the NEW machine:

    *.330  and  *.dat
