# Installing an extended evaluation license
<a name="setting-up-evaluation"></a>

When you request an extended evaluation license from Amazon DCV, you receive a `license.lic` file that defines the license. 

**To install the extended evaluation license**  
Place the `license.lic` file in the following folder on your server:
+ Windows server

  ```
  C:\Program Files\NICE\DCV\Server\license\license.lic
  ```
+ Linux server

  ```
  /usr/share/dcv/license/license.lic
  ```

Or, to place the `license.lic` in a different folder on the server, you must update the `license-file` configuration parameter so that it specifies the full path for the license file.

**To update the `license-file` configuration parameter on a Windows server**

1. Open the Windows Registry Editor.

1. Navigate to the **HKEY\_USERS\\S-1-5-18\\Software\\GSettings\\com\\nicesoftware\\dcv\\license\\** key and select the **license-file** parameter.

   If there is no `license-file` parameter in the registry key, create one:

   1. Open the context (right-click) menu for the **license** key in the left pane and choose **New**, **String Value**.

   1. For **Name**, enter `license-file` and press **Enter**.

1. Open the **license-file** parameter. For **Value data**, enter the full path to the `license.lic` file.

1. Choose **OK** and close the Windows Registry Editor.

**To update the `license-file` configuration parameter on a Linux server**

1. Navigate to `/etc/dcv/` and open the `dcv.conf` with your preferred text editor.

1. Locate the `license-file` parameter in the `[license]` section, and replace the existing path with the new full path to the `license.lic` file.

   If there is no `license-file` parameter in the `[license]` section, add it manually using the following format:

   ```
   license-file = "/{{custom-path}}/license.lic"
   ```

1. Save and close the file.
