A Microsoft License Pack (MLP) is a license agreement product that authorizes the making and use of one (or more, if indicated on the MLP) additional copy of a specified, previously licensed, Microsoft product. This product does not contain any disks. For example, if you work in a small company with two computers, and you need to use Microsoft Word on both computer systems, you could purchase a single copy of Microsoft Word and a single-copy MLP for Word. This would allow you to legally install Word on the first computer, as outlined in the Word End-User License Agreement, as well as on the second computer, as permitted by the MLP license agreement.
