Update to the Latest Software

Support for STELLA/iThink v10 Ending Soon

Last year, isee systems introduced our latest software Stella Architect. Stella Architect is replacing STELLA/iThink 10.1 as our flagship Systems Thinking software. By the end of April 2017, STELLA/iThink 10.1 will no longer be supported. Moving forward, we will only be developing and supporting the latest versions (currently 1.2) of Stella Architect/iThink, Stella Professional, and Stella Designer.

Have questions? Need to upgrade from a version prior to 10.1?

Give us a call 1-603-448-4990 or email support@iseesystems.com.

How do I get the new software?

Faculty Licenses

All customers who have STELLA/iThink 10.1 faculty licenses automatically have Stella Professional in their accounts at no additional cost. All faculty license support contracts have been switched from 10.1 to Stella Professional. Support on Stella Professional will require renewal on an annual basis to continue getting technical support and maintenance.

If you would like to sidegrade your faculty license to Stella Architect, please contact support@iseesystems.com or call (603) 448-4990 to request a quote.

Lab Licenses

Upon request, 10.1 lab licenses can be swapped for Stella Professional licenses. You just need to send an email to support@iseesystems.com or call (603) 448-4990. There is no charge to do this. Please remember that swapping the licenses to Stella Professional will not extend the support contract on your lab licenses.

If you would like to sidegrade your lab licenses to Stella Architect, please contact support@iseesystems.com or call (603) 448-4990 to request a quote.

Site Licenses

All customers who have a STELLA 10.1 Site License automatically have a Stella Professional Site License in their accounts at no additional cost. All site license support contracts have been switched from 10.1 to Stella Professional. Support on Stella Professional site licenses will require renewal on an annual basis to continue getting technical support and maintenance.

If you would like to sidegrade your site licenses to Stella Architect, please contact support@iseesystems.com or call (603) 448-4990 to request a quote.

Stella Professional or Stella Architect?

Stella Professional includes the functionality included in the Map, Model, and Equation layers of STELLA and iThink 10.1 - plus much, much more. You can build and simulate models with Stella Professional.

Stella Architect (also iThink) includes Stella Professional plus tools for adding Interfaces to your models, like the Interface layer in 10.1. Stella Architect also can be used to publish models to the isee Exchange web site, similar to isee NetSim.

If you want to add Interfaces to your models, then you will need Stella Architect.

Is it different from what I’m used to?

The software will feel very familiar to STELLA/iThink users. At the same time, some things will need getting used to. Overall, we’re confident you will be happy with the end result. Most users have been able to make the transition without difficulty. All of the concepts remain the same. However, some features may require different user actions.

We are committed to helping you as much as possible through this process. There are several resources available to help you migrate:

Webinars

Documentation

Books

Model Compatibility and Conversion

Models saved in versions 10.0 and above will open in Stella Architect and Stella Professional. Please note that once they are saved in the new software they are not backward compatible, i.e., you will not be able to open the models in version 10.0 or 10.1.

Models saved with versions prior to 10.0 (that have a .itm or .stm extension) can be opened in your copy of STELLA/iThink 10.1, saved, and then opened in the newest software. If you have problems converting your models, please email support@iseesystems.com with your attached model so that we can help you.
