ExtendSim 10.0.4 was released on March 19, 2019.

The prior release, ExtendSim 9.2, was released on February 13, 2015.

If you are using ExtendSim 9 or earlier, we recommend you upgrade to ExtendSim 10.

Most companies find it cost effective to install a mix of ExtendSim license types depending on team member usage. Our suggested guidelines are:

Team members using ExtendSim for long periods of time or intensely during the day - so full-time users - will need Individual licenses.

If you have 3 or more part-time ExtendSim users, a Floating license might be your most cost-effective option.

If you have a computer in a secure environment that needs to be accessed by multiple team members, install a Node-Locked license.

All 3 license types are available for all Model Developer Editions of ExtendSim: CP, DE, and Pro.

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.

Please contact Imagine That Inc. if you have questions about ExtendSim legacy products.

The ExtendSim License Agreement for an Individual license states:

"A single identified individual (the “Authorized User”) may use the Software. The Software may be used by the Authorized User only for the Company’s own internal business purposes or for your own personal use (if you are an individual), as applicable. Shared use, use by more than one individual, or use over a local-area network (LAN), a wide-area network (WAN), or the internet is prohibited under this License Option."

This means you are permitted one activation of your ExtendSim license for your own use. You may move your license from one of your computers to another at any time. But will have to deactivate ExtendSim on the first computer before it can be activated on a second as ExtendSim will not permit an additional activation.

Details on activating and deactivating ExtendSim licenses can be found at Installing & Activating an ExtendSim 10 Individual License.

Within the first 30 days of purchase, registered users are entitled to 100% trade-in credit for each Individual license converted to a station on a comparable or higher Floating license product.

If it has been more than 30 days since purchase, registered users with a current license are entitled to 75% trade-in credit for each Individual license converted to a station on a comparable or higher Floating license product.

If you are using a version prior to the current version, the trade-in credit will be reduced by the price of the upgrade.

Does ExtendSim have a VPAT showing its compliance with Section 508 of the Rehabilitation Act (accessibility of data and information to people with disabilities)?

Yes. Please see ExtendSim Section 508 VPAT (Voluntary Product Accessibility Template).

We could set up dozens of matrixes and comparative documents that boast about how awesome ExtendSim is and slant the results in our favor since we would be 'authoring the study'. But that's not right as your needs are vastly different that most others. We are happy to give you guidelines about how ExtendSim is designed and how it would handle the various challenges you could put it up against. But in the end, you are the best determinant of which tool would best suit your particular needs.

So, ask us questions - any question - and we're happy to tell you how ExtendSim works. If you want to know how it is as compared to other packages, we could provide you with our personal opinions, but it's probably best to ask those that have used multiple packages in their modeling careers. Check out what other simulationists are saying in the ExtendSim Exchange.

Yes and no... and yes it will! Confusing? Let us explain. 

The application gurus at Imagine That Inc. are hard at work on the Mac version of ExtendSim 10 right now. It should be just like the Windows version, but able to run natively on a Mac. And you will be able to exchange your ExtendSim models back and forth with colleagues between the 2 operating systems. We don't have a specific date when ExtendSim for Mac will be ready, but we will keep you updated.

What are my options today?

Run the Windows version of ExtendSim on your Mac, but in the Windows operating system. To do this, you need to obtain the Windows operating system and an emulator. You can use Boot Camp Assistant (installed with the Mac operating system in the Utilities folder under Applications). Or install the emulation software Parallels (www.parallels.com). During installation, Parallels will request the Windows operating system installer to complete the process. Once the installation is complete, you can install the Windows version of ExtendSim.

Run the Windows version of ExtendSim on a Windows computer.

Do earlier versions of ExtendSim for Macintosh run on current Mac systems?

Legacy versions of ExtendSim (9 and earlier) did have version that would run on Macs, but they will NOT run on current Macintosh operating systems OS X 10.7+. Legacy versions of ExtendSim for Macintosh can run on Mac OS X 10.6.8 and earlier. If you are using a Macintosh with OS X 10.7 or newer, use the Windows version of ExtendSim running in Parallels or BootCamp.
