Which license do I have, and how is it served?¶
Two independent questions: what type of license it is, and how it's served to your machine.
Run Help → Licensing (or und license) to see your current status.
License types¶
| Type shown | Meaning |
|---|---|
| Commercial License | A paid license (may show – Perpetual). |
| Trial License / Timed Trial | Time-limited evaluation. |
| Non-Commercial | For non-commercial use. |
| Educational | For qualifying educational institutions. See Apply for an educational license. |
| Corporate | A corporate-wide license (shown separately from the normal per-seat info). |
| Open Source | Automatic free grant for projects in a public git repository. See Use Understand free for open-source projects. |
Note
These are the type names Understand reports; a perpetual license appends – Perpetual (e.g. "Commercial License – Perpetual"), and a corporate license shows as its own Using Corporate License line rather than as a type name. (There is no separate "FOSS" license type — non-commercial use falls under Non-Commercial.)
How the license is served¶
| Mechanism | What it means | How to point at it |
|---|---|---|
| Cloud (default) | Licenses served by SciTools' cloud server, licensing.scitools.com. | Default; no action. |
| On-premises server | Your organization hosts its own Icarus license server. | Set the server with und -setlicenseserver <host>, or the UNDERSTAND_LICENSE_SERVER environment variable. |
| Offline | No network at all; codes exchanged via scitools.com/offline. | See Check out an offline license. |
| Node-lock | License bound to one specific machine. | und -createnodelockrequestcode → redeem → und -setnodelockreplycode <code>. See node-lock codes. |
Concurrent/floating seats are served by the cloud or on-prem server and are freed when you close
Understand or return the seat — see Manage a team — seats and usage. All
the license-related und switches are in the und licensing reference.
Redeeming a claim code¶
A claim code is not a license code — redeem it at licensing.scitools.com to get your license, then enter that in Help → Licensing. Step-by-step: Redeem a claim code & enter your license.
