I have a purchased version of Mach3 running on a Windows XP stand alone  computer.  I want to purchase a license to use the Mach3 mill wizards.
Does my stand alone computer need to be connected to the internet to download the product license key? 
Can I download the license on my internet  connected computer and use the wizards on this computer that does not have Mach installed?
Thank you all in advance
