I'm installing Adobe Creative Package onto an new Imac (Imac16,1/OS X El Capitan).  During insall I'm at the point where it requires package details.  My intention is to create a master image on this iMac.  Should I select in the "Serial Number Licensing "  the Serial Number Licence, or Named License?  This is my first interation with Adobe, and an Imac.
