A valid License is required to create or edit simulations. There are 2 licenses options, a design license allows individual users to create and edit multiple individual simulations. A manage project license is for a single simulation of an existing operation and allows any user to own or edit that simulation without the need for an individual license. Long term design licenses entitle users to telephone and email support while the license is active, and for the first year online training and support is provided to begin use of AggFlow at no additional charge. For monthly subscribers online training and support is available at standard consulting rates. AggFlow can be downloaded and installed and used in read only without a licence, or used to access any licensed Manage Project depending on your user rights.
