    b. For SE Zips, select 'Unzip'. After the file(s) have been unzipped, click 'Close'.
3. Verify that the update has been correctly applied.
     (This usually entails checking both the program and data version info shown at the bottom of the Main Menu.)
4. Delete the "Update..." icon from your desktop or move the file to an archive media.
