Updating MICRODEM

Windows itself, and IT departments, combine to make it hard to have MICRODEM update itself.  There are too many variants of Windows and network security to make this easy to track down, and the anti-virus companies have also used racial profiling tactics to block automatic downloads.

Options for new EXE

  • Pick "Close program and update" option on Tools popup from  file menu.  This will close MICRODEM and any open  maps.  It will download the latest MICRODEM EXE from the USNA server, and if you have the "Backup EXE before web update" option set on the Web tab of the options form, it will  back up the old version first in  "c:\microdem\backup", with the date of the program appended to the name.  This option will restart the new MICRODEM.  The tools popup also lets you back up an old EXE if you find a bug, and if your favorite option has been changed in a way you don't like.
  • You must have write permission for the directory with MICRODEM.
  • Download from http://www.usna.edu/Users/oceano/pguth/website/microdem/microdemdown.htm where you must right click on the links, "save target as", and insure the location is "c:\microdem".  Insure the browser does not change the file names, like adding "(1)".

Options for new help file:

  • Download the latest help file from Tools popup on file menu.  This should work with no problems, as long as the help file is not open.
  • Download from http://www.usna.edu/Users/oceano/pguth/website/microdem/microdemdown.htm where you must right click on the links, "save target as", and insure the location is "c:\microdem".
  • If you cannot see the content, you need to unblock the help file.  Right click on it in Windows Explorer, and the unblock option should be on the lower right of the form.
