# Downloading the Installer

How to download the ENERCALC SEL installer and locate it after download using your Product Control Code.

### How do I download the installer?

Installation of ENERCALC SEL is handled by the program located at this link:

<a href="https://install.enercalc.com/ECSEL20_SETUP.EXE" class="button primary" data-icon="download">Download the ENERCALC SEL installer</a>

This installation program asks for your Product Control Code (PCC), so it can determine the most recent version of the software you are allowed to run. It then downloads the installer and proceeds.

Sometimes the downloaded installer cannot run because of restrictions caused by a Windows program launching mechanism. In this case you need to contact <support@enercalc.com> and request a simplified installer for your license. (Always provide your “KW” User Registration Number any time you contact ENERCALC.)

### How do I find the installer once it's downloaded?

* Check the download strip at the bottom of your browser window.
* In Google Chrome, select **Customize and control Google Chrome**, then select **Downloads**.
* Open File Explorer, then navigate to `\Downloads`.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enercalc.com/docs/sel-faq/setup-and-licensing/installation/downloading-the-installation-p.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
