Use of the software means that you have loaded the program and run it or have installed the program onto a computer. If you install the software onto a multi-user platform or network, each and every individual user of the software must be registered separately. Networked use of the application will involve purchasing the required number of copies. One registration key will be provided. The application will then have to be installed and registered on each client machine.
Purchases are cumulative.
An example is if you bought one copy of the application and used it on one computer. You then wish to use it on all ten of your computers. Unlimited Site License Purchasing 250 copies of the application grants you an unlimited site license.
