# ownCloud 9.0 Server Administration Manual

# License Keys

## Introduction

You’ll need to install a license key to use ownCloud 8 Enterprise Subscription. There are two types of license keys: one is a free 30-day trial key. The other is a full license key for Enterprise Subscription customers.

You can download and try ownCloud 8 Enterprise Subscription for 30 days for free, which auto-generates a free 30-day key. When this key expires your ownCloud installation is not removed, so when you become an Enterprise Subscription customer you can enter your new key to regain access. See How to Buy ownCloud for sales and contact information.

## Configuration

Once you get your Enterprise Subscription license key, it needs to be copied to your ownCloud configuration file, `config/config.php` file like this example:

    'license-key' => 'test-20150101-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-YYYYYY’,

Each running instance of ownCloud requires a license key. Keys will work across upgrades without issue, so new keys will not be required when you upgrade your ownCloud Enterprise Subscription to a new version.
