Activation Code or Purchase Key explanation

Problem:

What is the "Activation Code" or "Purchase Key" and what's the difference with a "Serial Number" ?


Solution:

The "Activation Code" or "Purchase Key" is the code you get when you buy a GrandVJ or MediaMaster license.
That code must be used along with another code, the computer's Machine ID Code (generated by the installed software), to create a final Serial Number that will allow activating the software on the computer.
