# Installing License Key

Uvuyo needs a license key to run. If you don’t have a license key, uvuyo will run with a temporary license after install. The temporary license key is valid for 30 days. You will need a permanent license key to run uvuyo after the temporary license key expired. Contact 2yetis sales if you don't have a license key and would like to use the product after the temporary license key expired.

Be aware that you are not allowed to run uvuyo in production with a temporary license key. Also you are not allowed to reinstall uvuyo after your temporary license has expired.

You install the license key in the `$UVUYO_HOME/etc/default.properties` file. There you need to set the two parameter `uvuyo.license.owner` and `uvuyo.license.key` to the values you got when you retrieved the license from 2yetis. The $UVUYO_HOME directory is the directory in which you have installed uvuyo. This is typically /opt/2yetis/uvuyo on linux systems and c:\Programm Files\uvuyo on Windows systems.

 Note

If the file does not exists you would need to create the file.

Parameters:

| Parameter | Description |
| --- | --- |
| uvuyo.license.owner | The entity that owns the license. Make sure that you type the owner exactly how you got it from 2yetis, else the node is not going to start. |
| uvuyo.license.key | The license key provided by 2yetis. Again ensure that you have no typos in the key, else the node is not going to start. |

Example:

```
uvuyo.license.key=3de8-cb9d-d74a-1cd0-4105-6682-35cf-ed17-0813-cc91-4910
uvuyo.license.owner=MyCompany
```

The license file is validated during startup of the product. If you do not have a valid license key, the product will not start you are will get an error message in the uvuyo log file.
