1.Install LightWave 
2.Start Lightwave, when you are asked for a license 
  simply DRAG XF_LICENSE.LWK into the Windows
  (or you can copy it to the bin folder
  before starting lightwave)
  OR just copy it here :
  C:\Users\[USER]\.NewTek\LightWave\2015.3\licenses\

  We have included 5 licenses with 5 different dongles

3.That's it .

NB : if you have previous fake licenses or those
     patched dll, clean your mess first
     licenses are stored either in the bin folder
     or in your user profile
     c:\Users\[USER]\.NewTek\LightWave\2015.3\licenses\
