The Demo is a limited version of ExtendSim designed for those want to:

	Evaluate the ExtendSim line of products
	Run models built by others

The ExtendSim Demo is available as a free download. It includes a limited version of ExtendSim featuring all four products, plus manuals in .pdf format and example models that illustrate ExtendSim capabilities.

While you cannot print or save with this non-expiring Demo, you can:

	Explore the features and capabilities of the four ExtendSim products (ExtendSim Suite, ExtendSim AT, ExtendSim OR, and ExtendSim CP)
	Use it as a Player to run models of any size and view simulation results
	Build (but not save) small models (75 blocks or less)
	Change (but not save) parameters in any size model
	Add or remove blocks and change connection lines in existing small models (75 blocks or less; additions and changes are not saved)*
	Create new blocks and save them in libraries
*	Full versions of the ExtendSim products allow you to build models of any size, save changes to existing models and save the models themselves, print model worksheets, and use scripting to automatically construct a model.

Although the following capabilities are available in the full version, with the Demo you cannot:

	Save models you build
	Save changes to existing models
	Print model worksheets
	Use scripting to automatically run or construct a model

For more capability, see the LT-RunTime version of ExtendSim.

Demo example models

When you launch the ExtendSim Demo, the file Demo.mox is automatically opened. This file contains a selection of sample models for each ExtendSim product, a description of the model, and descriptions of the ExtendSim products. To open other models, use the File > Open command. Example models are designed to help you evaluate ExtendSim. With them you can:

	Learn about ExtendSim capabilities such as 3D animation, linking to internal databases for data storage and management, optimization, hierarchy, built-in authoring environment, activity-based costing, and interacting with Microsoft Office and other applications
	Determine which ExtendSim product is right for you: ExtendSim Suite, ExtendSim AT, ExtendSim OR, or ExtendSim CP

Demo License Agreement

The ExtendSim Demo is licensed for your personal use on a single computer. It is covered by a License Agreement that restricts its use, deployment, and distribution. Among other restrictions, unless you have obtained the prior written consent of Imagine That Inc. you may not include the Demo on a CD or any other media nor place the Demo for direct download from your web site. (You may, however, place a link from your web site to our web site’s download location.) See the ExtendSim License Agreement for complete terms.

ExtendSim LT-RunTime is a limited version of ExtendSim that has more saving and printing capability than the Demo version and allows you to run models of any size for an unspecified time period. It is designed for:

	Students building small (75 blocks or less) models for classwork.
	Potential customers who are evaluating the ExtendSim line of products and need more capability than the free Demo version.
	Customers who don’t have ExtendSim but want to use models built by others.

The LT-RunTime application has many capabilities. For example, you can:

	Explore the features and capabilities of the four ExtendSim products (ExtendSim Suite, ExtendSim AT, ExtendSim OR, and ExtendSim CP)
	Build and save small models (75 blocks or less), or make changes to existing small models (75 blocks or less), for a limited time (180 days).
	Run models of any size, change parameters, view simulation results, and save the changes. This capability does not expire.
	Create new blocks and save them in libraries.
	Print model worksheets, block dialogs, and so forth.

However, there are some limitations:

	The models you build are limited to a maximum of 75 blocks.
	The model-building capability expires 180 days after installation. (Note: model-running capability does not expire.)
	You cannot use ActiveX automation to run or construct a model.
	There is no upgrade path and technical support is limited to installation questions.

Among other restrictions, unless you have obtained the prior written consent of Imagine That Inc. you may not allow others to access the use or functionality of the ExtendSim LT-RunTime, nor include the LT-RunTime on a CD or any other media.

The ExtendSim Maintenance Subscription is the solution for ExtendSim customers who:

		Want a cost-effective method to keep their ExtendSim licenses current.
		Prefer the convenience of budgeting for an annual payment.

How does the Maintenance Subscription work?

You have the option to purchase an ExtendSim Maintenance Subscription when you purchase or upgrade ExtendSim (single user licenses only). Major upgrades (whole number version changes) released during your maintenance year will automatically be shipped to you. You will be invoiced annually to renew the Subscription so that you can continue receiving regular upgrades. (Policy on late or lapsed Maintenance.)

		Cost of shipping the upgrade is included in the annual fee.
		The Maintenance Subscription is only available when you purchase or upgrade your ExtendSim license.
		If your Subscription order includes multiple ExtendSim licenses, the CD containing the upgrade will be shipped to one location within your company as specified by you. Note: Each license must have its own separate Maintenance Subscription.
		Minor updates and bug fixes between version changes may be downloaded from our web site.
		Outside the U.S. and Canada, please contact your local representative.

How much does it cost?

The price is calculated based on the ExtendSim package you are purchasing or upgrading. Each license must have its own Maintenance Subscription.

Why should I opt for a Maintenance Subscription rather than just pay the upgrade cost at the time of release?

The Maintenance Subscription is designed to help with budget planning and avoids the cost of processing purchase requisitions for upgrades.

If you do not purchase the Subscription and you wish to upgrade to the current version of ExtendSim at a later date, it may cost you more. The upgrade price is variable, depending upon features included in each release.

Do I need a Maintenance Subscription if I own an ExtendSim Network License?

No. An ExtendSim Maintenance & Support Plan is already included in all Network (Concurrent User and Lab) Licenses

These custom license give you the right to distribute either the Demo-Player or LT-RunTime versions of ExtendSim on a CD.

An ExtendSim ASP license gives the licensee the right to access or to provide access to the functionality of ExtendSim over the internet or an intranet through a front end (wrapper) application. An ExtendSim ASP license is a great solution for organizations who:

	Want the benefits and capabilities of simulation without deploying ExtendSim licenses to end users
	Prefer centralized control and management of ExtendSim models
	Choose to access the functionality of ExtendSim via an intranet or the internet
	Have few or no end users with simulation interest or expertise
	Prefer an ASP (Application Service Provider) or Software-as-a-Service (SaaS) approach to software licensing
	An ASP license gives the licensee the right to access (or in the case of service providers, to provide access to) the full functionality of ExtendSim over an intranet or the internet utilizing a customized license of ExtendSim AT.

The ExtendSim ASP license is typically used in combination with a front end (wrapper) application developed either by the licensee organization or by a third party. The wrapper environment uses a COM interface to send data to ExtendSim, run a model, and retrieve results. It accesses the functionality of ExtendSim while presenting end users with a standardized front end, across multiple models, for data entry and the reporting of results.

The combination of an ExtendSim ASP license with a wrapper environment has the advantages of remote access via the web, centralized feature updating, and lower learning curves for non-modelers.

The ExtendSim ASP license is priced per server installation.

	If you place the ExtendSim logo on the front end of your access point with a link to the ITI site, the cost is $10,000 plus an annual renewal fee of $2,000 per year after the first year.
	Without the logo and front end link, the cost is $25,000 plus an annual renewal fee of $5,000 per year after the first year.

The OEM (Original Equipment Manufacturer) license is for system builders who want to embed the simulation power of ExtendSim within their own applications. This license gives you the customized right to use and/or sell your product bundled with ExtendSim under your branded name.

Pricing starts at $50,000. Please contact Imagine That Inc. for a personalized quote based on your intended usage.
