# Purchase licenses

You can purchase Parallels RAS licenses online or you can contact a Parallels partner.

## **Purchase licenses online**

Visit <http://www.parallels.com/products/ras/buy/>

## **Purchase licenses through a Parallels partner**

To find a Parallels partner near you, visit <http://www.parallels.com/partners/locator/>

Once you purchase licenses, the Parallels partner will provide you with a single license key which you can use to activate Parallels RAS. You only need one key to register and activate all your licenses.

If you don't already have a Parallels account, you will also receive an invitation to join one.

**Important:** A license key can be used to activate a single installation of Parallels RAS. You can change the activated installation up to three times (for backup purposes, if a previously activated server has been damaged or stolen, etc.). If you need to activate several Parallels RAS installations to work simultaneously, you need multiple license keys.

## 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.parallels.com/landing/ras-licensing-guide/purchase-or-upgrade-licenses/purchase-licenses.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.
