Our end user license agreement for Visio shapes, as well as for our add-on products, authorizes the user to install it on one or more machines only for use by the person that purchased it. For example, if you have a desktop machine and a laptop for traveling, you may install and use the product on both machines.
However, each individual user must own a license for each product. For example, if a company purchases a ShapeSuite they must purchase a license for each individual user. For details, please refer to the file EULA.txt that is accessible from the Support tab of any product page.
