How to apply a field upgrade:

- Connect the spectrometer to be upgraded to the PC with a USB cable. 
  Do not connect more than one spectrometer at a time.

- Start the 'fieldupgrade.exe' installer by double clicking it in Windows
  Explorer or by selecting 'Run' from the Start menu and browsing to the
  file 'fieldupgrade.exe'. The extension '.exe' may not be visible, depending
  on the settings of your computer.

- Start the 'apply_update.exe' by clicking the 'ApplyUpdate' icon on the desktop. 
  You can also start it from the Start Menu, where 'apply_update' is located in the 
  'AVANTES Software' folder.

- In the 'AvaSoft Application Module Activation Utility', Select 'File', 
  'Load Update File' and select the password file.
  There will generally only be one choice, the file has a .pwd extension.

- Click the 'Apply Update' button. The program will show a messagebox to
  signal success or failure of the upgrade.
  The upgrade will fail if the spectrometer is not connected to the PC.
  It will also fail if the serial number does not match the recorded one.
