It is always highly recommended to use the most current release of any software tool – as is the case with ExtendSim. Current releases take advantage of hardware and software advances and interact more appropriately with other new software packages. Plus, the current release of ExtendSim 10 can run models that were built in ExtendSim 9, 8, and 7.

However, there are reasons you might need to use a legacy ExtendSim product:

If ExtendSim 10 has not yet been approved for use by your company or organization.

Your collaboration team is still using ExtendSim 9 and you are working towards transitioning them to 10.

You are a student and your course materials use ExtendSim 9. (Many professors will not be updating their materials until 2019.)

ExtendSim 9 will only be available for purchase for one year following the release of ExtendSim 10 and is subject to annual Maintenance & Support fees. Please click on the icon of the legacy package you wish to purchase:

ExtendSim Suite 9 ExtendSim AT 9 ExtendSim CP 9 ExtendSim Student 9
ExtendSim Suite 9 ExtendSim AT 9 ExtendSim CP 9 ExtndSim Student 9

Note: As ExtendSim 9 is legacy software, it will no longer be updated or guaranteed to run on future operating systems.
