# Moving the Activation to a Different Computer

How to move your ENERCALC license activation from one computer to another using Internet Deactivate and Activate.

## How can I move my activation to a different computer?

Use “Internet Deactivate” on the currently active computer.

Go to the other computer and use “Internet Activate”.

The activation system can also remotely deactivate the first computer if you forget. Very convenient!

## What if I don’t deactivate from my computer prior to moving the activation to another computer?

The activation system contacts our activation server for permission. If the activation server knows that another computer is currently active, it will give you the option of deactivating it. The next time you start the SEL on the other computer it will indicate that it has been deactivated.

## 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/making-changes/moving-the-activation-to-a-dif.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.
