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 Fall semester 2019.)

ExtendSim 10 was released October 2018, relegating ExtendSim 9 to legacy status. The final update of ExtendSim 9 was 9.3 on June 25, 2019 and there will be no further ExtendSim 9 updates. We will continue selling ExtendSim 9 through 2019 but it is no longer supported and we cannot guarantee that it will run on future operating systems based on unforeseen OS modifications.

If you would still like to purchase this legacy software, please choose the 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
