A Modeler License can be one of five types: Subscription, Evaluation, Permanent, Incremental or Upgrade.

A subscription license is a temporary license, usually valid for one year, that can be borrowed to allow users to work with Modeler while disconnected from the license server.

An evaluation Modeler license allows you to start Modeler after installing the product. The evaluation type expires after a specific number of days, so for use of Modeler after the Modeler license has expired, you must obtain a permanent or a subscription Modeler license from PTC. If you have purchased a server-based floating license, the correct number of evaluation Modeler Licenses will be provided. The evaluation Modeler license is supplied in the cover letter that accompanies Modeler.

A permanent Modeler license allows you to use Modeler after the evaluation Modeler license has expired. Use License Manager to create a license request for a permanent Modeler license, and then send this license request to PTC. PTC can then send you a permanent Modeler license. A permanent Modeler license works only on the computer from which the license request was made.

If you are using a server-based floating license, you can add additional licenses to that license by adding an incremental Modeler Licenses to the license file. Use License Manager to create a license request for an incremental Modeler License, and then send this license request to PTC. PTC can then send you an incremental Modeler license. An incremental Modeler license works only on the computer from which the license request was made.

An upgrade Modeler license upgrades a permanent or incremental Modeler license to work with a new release of Modeler. An upgrade Modeler license works only on the computer from which the license request was made. Users that have a maintenance agreement with PTC should receive an email that provides instructions for obtaining an upgrade Modeler license.
