Additional users are licensed, among other things, by extension package (e.B. up to 99 users) that contains the basic package (e.B. 5 users). Some programs are modular, so you need to buy a basic product before you can use other modules.  Some licenses claim to prohibit a user`s right to share data about the performance of the software, but this has not yet been challenged in court. The most important effect of this form of license is that if ownership of the software remains the property of the software publisher, the end user must accept the software license. In other words, without accepting the license, the end user may not use the software at all. An example of such a proprietary software license is the license for Microsoft Windows. As usual with proprietary software licenses, this license contains a long list of restricted activities, such as. B: reverse engineering, simultaneous use of the software by several users and publication of benchmarks or performance tests.
These software licenses do not authorize the software to copy, modify, or distribute. This is the most restrictive type of software license that protects the developer or owner from unauthorized use of the software. An example of a free software license with copyleft is the GNU General Public License (GPL), also the first commonly used copyleft license. This license is intended to give all users unlimited freedom to use, study, and modify the software privately, and if the user complies with the terms of the GPL, the freedom to redistribute or modify the software. For example, all changes made and redistributed by the end user must include the source code of the changes, and the license of a derivative work must not impose additional restrictions beyond what the GPL allows.  Software license agreements vary widely and are based on many different factors, including the type of software licensed. A software license agreement can be: Proprietary software licenses – do not provide such authority for code modification or reuse and generally provide the software only with exploit code and no source code. A proprietary software license often contains terms that prohibit “reverse engineering” of object code with the intention of obtaining the licensee`s source code. The four sections listed above provide only a brief overview of what you can expect from a standard software license agreement. There are certain key clauses that you want to include to make sure you are well protected, no matter what happens in the future. While it`s hard to predict everything that may happen, you can take the time to make sure you protect yourself as much as possible by including these essential clauses. Some end-user license agreements accompany shrink-wrapped software, which is sometimes presented to a user on paper or usually electronically during the installation process.
The user has the choice to accept or refuse the contract. The installation of the software is subject to the condition that the user clicks on a button labeled “Accept”. .
