Hi (completely different question from the one i asked an hour ago),
When you purchase a windows software, you can only use it or install it in your computer when you have the key and the license. Sometimes they even ask you for your mac address than they give you a license.
How can i do that for the software i am developing? I am starting (haven't started yet :) ) a business and want only the people that have paid to use the application i am developing.
Thanks very much in advance.
