I have purchased the "Agency (or multi-user)" edition of an AbleLink Desktop program. What are the restrictions on how many people and machines that I can use?

The agency, or multi-user, edition entitles the user to a single desktop computer license. The software itself allows for multiple users to each login to their own customized environment on a single computer. The number of users on the single computer is unlimited. However, if your need is for the program to exist on multiple computers then you will need to purchase a separate license for each computer on which it is to be installed.
