# License Key

Starting with Keeper Connection Manager version 2.19, customers are required to obtain a license key from Keeper in order to continue the use of the application.

{% hint style="info" %}
Before installing KCM 2.19 or later versions, please ensure you have a valid license key. **Without a valid license key, users and administrators will be unable to use KCM after the update is applied**
{% endhint %}

#### Obtaining a License Key <a href="#obtaining-a-license-key" id="obtaining-a-license-key"></a>

To obtain a license key, please contact Keeper Support directly at: <https://www.keepersecurity.com/support.html>

Upon request, Keeper Security staff will generate and send a copy of your license key.

#### Installation

To install your license key, you must provide the license as the sole contents of `/etc/guacamole/kcm.license`, which must be readable by the guacamole group.

```
cat "license_key_supplied_by_keeper" > /etc/guacamole/kcm.license
chmod 640 /etc/guacamole/kcm.license
chown root:guacamole /etc/guacamole/kcm.license
```

After adding the license key, restarting the service may be necessary.

```
sudo systemctl restart guacamole guacd
```

## 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://newdocs.keeper.io/kcm-linux-rpm-method/installation/license-key.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.
