Support for, and new versions of, Vensim are provided on a subscription basis. Your initial licensing of Vensim includes one year of maintenance. At the end of that time you must renew your maintenance to continue to receive new releases and technical support. Maintenance gives you access to all new versions of Vensim for the configuration you have licensed. These can be downloaded from our web site
http://www.vensim.com
If you choose not to renew maintenance you may, unless you have a limited time version, continue to use the software, but you will not have access to new releases or technical support.
Technical support is available for problems relating to the installation and use of the Vensim Software. Technical support does not cover issues in conceptualization and formulation which can best be addressed through training or consulting.
Training is available both for the use of Vensim and the art and practice of building system dynamics models. Public workshops are offered periodically and workshops can also be delivered in-house when that is appropriate.
Ventana Systems, Inc. provides a full range of consulting services. We can provide you with the expertise you need to address difficult business problems.
