# Importing a Licence Update – LumiScan Licensing

When HD Vision Systems has processed your [licence request](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.3/requesting-a-licence-update.html), you receive a licence update file (`.WibuCmRaU`). Its file name contains the serial number of the LumiScan Key it is intended for.

> [!IMPORTANT]
> Do not remove the LumiScan Key while the licence update is being written.

## Importing with the CmFAS Assistant

1. Save the `.WibuCmRaU` file on the PC to which the LumiScan Key is connected.

2. Check that the serial number in the file name matches the serial number of your LumiScan Key.

3. Open **CodeMeter Control Center**.

4. On the **License** tab, select your LumiScan Key on the left and click **License Update**.

   The CmFAS Assistant opens.

5. On the welcome page, click **Next**.

6. Select **Import license update** and click **Next**.

7. Click **…**, select the `.WibuCmRaU` file and click **Commit**.

   The licence update is written to the LumiScan Key.

8. Click **Finish**.

The new licences are available immediately. LumiScan applications that are already running may have to be restarted to use them.

## Importing from the menu

You can also import the update file without the CmFAS Assistant:

1. In CodeMeter Control Center, select **File > Import License…**.

   ![CodeMeter Control Center File menu with Import License](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.3/_images/cc-file-import-license.png)

2. Select the `.WibuCmRaU` file and click **Open**.

   ![File dialog with a .WibuCmRaU file selected](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.3/_images/import-file-dialog.png)

> [!TIP]
> You can also drag the `.WibuCmRaU` file onto the CodeMeter Control Center window.

## Importing on the command line

On a PC without a graphical interface, use `cmu` (on Windows: `cmu32` in the **CodeMeter Command Prompt**). Replace `3-1234567` with the serial number of your LumiScan Key:

```bash
cmu --import --file 3-1234567.WibuCmRaU
```

If the import fails with error 705, see [Error 705 during import](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.3/troubleshooting.html#error-705).
