Installation of ENERCALC SEL is handled by the program located at this link: 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 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 in the strip at the bottom of the browser window * In Google Chrome, you can click "Customize and control Google Chrome" (the button in the upper right with 3 dots) and then click Downloads * Navigate to \Downloads in a File Explorer window.

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/downloading-the-installation-p.md?ask=&goal= ``` `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.
