# Glossary of Installation, Activation & Licensing Terms

Definitions of key ENERCALC SEL installation, activation, and licensing terms like seat, pool, PCC, and update.

**Activation** – the process of obtaining permission to run a seat of the ENERCALC SEL in “Licensed” or “Activated” mode. Activation is performed *after* installation.

**Changes** – alterations to the software that typically consist of bug fixes, spelling corrections, layout modifications, or system-wide behavioral modifications.

**Enhancements** – alterations to the software that generally consist of new modules, new calculations, or new codes and design standards.

**Installation** – one instance of a piece of software being installed on a computer. You install a piece of software, but by way of comparison, you do *not* install a “license”.

**Internet Activation** – the process of obtaining permission to run a seat of the ENERCALC SEL in “Licensed” or “Activated” mode by entering the Product Control Code into the software and transmitting a request for activation over the Internet to ENERCALC’s Activation Server. This process **does not** happen *every* time the software is launched on a given machine (unless the user has chosen automatic activation & deactivation).

**License** – describes the License Agreement that the user has entered into with ENERCALC. It can be thought of as something that is associated one-to-one with a KW User Registration number and that indicates how many “seats” are in the user’s “pool”. A “license” is intangible. A “license” is not delivered in the delivery email…that is a Product Control Code (PCC) or a Manual Activation Code (MAC). A “license” is not installed…software is installed. A “license” is not activated or deactivated…a seat of the SEL can be activated or deactivated.

**Maintenance & Support Plan (MSP)** – ***\[NO LONGER AVAILABLE]*** a fee-based agreement that entitles the user to technical support and to any and all Changes or Enhancements released in the form of Updates during the term of the agreement.

**Manual Activation** – the process of activating an installation with a machine-specific Manual Activation Code. If it is not possible to connect to ENERCALC’s Activation Server via the Internet, a user can request a Manual Activation whereby we email a Manual Activation Code that gets pasted into the program to provide a machine-specific activation. **Note! Manual Activation is not as convenient as Internet Activation, because a Manual Activation cannot be shuttled between computers like an Internet Activation can.**

**Manual Activation Code** – describes the machine-specific text string that ENERCALC emails to a user in order to allow them to perform a manual activation. (Manual Activation Code also used to be referred to as a “Manual Unlock Key”.)

**Pool** – the collection of seats allowed by the user’s license. The user’s “pool” can be thought of as existing in the ENERCALC Activation Server.

**Seat** – one activated instance of ENERCALC SEL or ENERCALC Cloud version.

**Update** – a new build of the software, or the process of installing a new build. This is something that is downloaded from the website and executed on the user’s machine. An Update can contain “Changes” and/or “Enhancements”.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/sel-faq/setup-and-licensing/installation-activation-lice/how-it-works/glossary-of-installation-acti.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
