What is a license?

Software is an intellectual property that requires a license for its usage.

A software license is the legal right to install, use, access, display, run a software program. Usage rights vary according to the type of license bought.

Usage Rights

End User License Agreement (EULA) – Governs a single software title acquired by an individual and software acquired with the purchase of a computer from an OEM, or FPP.

What is EULA?

EULA stands for End-User License Agreement. This is a legal document that governs the use of all software applications. Many people don't realize that when software is purchased, you do not "own" the software itself; you've actually purchased a license to use that software. The software publisher retains all rights, including copyrights, to the software and accompanying media. The EULA document outlines the terms of the software license, spelling out all rights and restrictions relating to the ownership, use, distribution, and warranty of the software product.
