  1. Installation using SETUP.EXE
  ===============================

  Within Windows 3.1 Program Manager select "File" - "Run", switch to the
  drive where your original Navigator 5.1 program disk resides and run
  SETUP.EXE.
  
  NOTE 1: If you encounter problems with the setup, close all other Windows
  applications before re-running the setup program again.

  NOTE 2: The setup program automatically expands the program files upon
  installation. Depending on your hardware configuration, this process may
  take several minutes to complete. Please be patient and await the end of
  the process without interrupting it.


  2. Errors when running the program
  ===================================

  If you have previously installed a Visual Basic application (or Visual
  Basic itself prior to version 3) on your system, you might have several
  outdated system files in your \Windows\System directory.

  If this is the case, Navigator will report that it can not run. A specific
  error message will name the offending files.

  The Setup program does not copy any files to your \Windows\System
  directory, in order not to overwrite any more recent files than those
  that come with Navigator 5.1 (possibly corrupting other applications that
  you have installed.)

  If Navigator starts with an error message, we recommend that you back up
  any offending files from your \Windows\System directory to a floppy disk.
  Then, copy the more recent versions of those files (mentioned in the error
  message) from the NAV51 directory to the \Windows\System directory,
  overwriting the old files with the newer versions.
  
  example:
  ========
  The error message reports problems with GRID.VBX.

  You may use Windows File Manager, but we suggest that you work in DOS to
  make sure that no Windows system file is currently active.

  Put an empty floppy disk in your disk drive.
  Enter copy c:\windows\system\grid.vbx a: <ENTER>
        copy c:\NAV51\grid.VBX c:\windows\system <ENTER>

  If the error messages mention files not present in the NAV51 directory
  the reasons might be the following :

   1) NAVIGATOR 5 has not been correctly installed.
   2) you do not have the correct WINDOWS version installed or
      several WINDOWS system files have been modified, deleted or
      incorrectly installed. Please check that you run WINDOWS 3.1 or
      compatible and/or consider re-installing WINDOWS.

  3. New utility: BGLNAV
  ======================

  BGLNAV is a DOS based utility that allows FS5 users who have additional
  sceneries installed to enter the corresponding navaid and airport data
  easily and effectively into the Navigator 5.1 data base.

  BGLNAV reads FS5 scenery files ("BGL files"), extracts navigation data
  contained in these files and creates text files that can be directly
  imported into the NAVIGATOR databases.

  To simplify BGLNAV operation for users of MS Windows, a Windows
  interface program, BGLNAVWN, is included.

  BGLNAV and BGLNAVWN having been added after the Navigator 5.1 manual
  went to print, these utilities could not be documented within the manual.
  The documentation for both utilities resides in your Navigator directory
  as BGLNAV.DOC and BGLNAVWN.DOC respectively. You may read and print it
  with any text editor or word processor.
