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.

ExtendSim 10 was released October 2018, relegating ExtendSim 9 to legacy status. The final update of ExtendSim 9 was 9.3.1 on October 28, 2019 and there will be no further ExtendSim 9 updates. ExtendSim 9 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:

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. See Moving ExtendSim from one computer to another.

Details on activating and deactivating ExtendSim licenses can also 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.

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 than most others. We are happy to give you guidance 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 (you can run ExtendSim on a Mac) and no (just not natively). ExtendSim is a Windows application, but there is a way to run Windows applications like ExtendSim on Macintosh computers.

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