There are several types of software license, in general they can be grouped into individual licenses, special channel licenses, multi-user licenses and network licenses.
This type of license allows the program to be installed and used on a CPU that is not accessible by other users over a network. The Software will only be used on a single computer, and other users will not be able to access or run the Software while connected to your computer. Types of individual licenses are:
- Perpetual license: allows the customer to install and use the software indefinitely. Technical support is included for a limited period, usually 90 days.
- Subscription License – Allows the user to use the software for a specified period of time. This license generally includes technical support and access to updates and patches released during the subscription period. At the end of the term, the user has several options: (1) renew the subscription; or (2) purchase a perpetual license at a discounted cost; or (3) remove the software from the computer.
- Freeware license: This type of license is offered as freeware by the author and does not require the payment of any fees for its use.
- Shareware License: This is a license to use the software for a trial period and then if you continue to use the software, you must pay a shareware fee or stop using the software.
Special channel licenses

This software will be identified or labeled “For distribution with new computer hardware only.”
