Upgrade versions are treated as part of the whole product, because an upgrade often needs many of the basic components in the original software in order to run. This is true for both application and system product upgrades. All copies together are treated as a single product, regardless of how many upgrade versions you ve acquired. However, as you acquire upgrades for the new product you must retain both the original product and the upgrade versions, which together serve as a single product. Since the original full product and the upgrade product together are considered a single software unit, you must retain the old product to remain legally licensed.
Software piracy is the unauthorized copying, reproduction, use, or manufacture of software products.
In some countries, up to 99 unauthorized copies are made for every authorized copy in use. Software piracy harms everyone in the software community including you, the end user. Piracy results in higher prices for duly licensed users, reduced levels of support, and delays in the funding and development of new products, causing the overall selection and quality of software to suffer. Piracy harms all software publishers, regardless of their size. Software publishers spend years developing software for the public to use.
