# Renewing Engineering Licences – LumiScan Licensing

Engineering apps bought from HD Vision Systems are licensed as an annual subscription. The licence on your LumiScan Key runs for one year and must be renewed with a licence update every year.

> [!NOTE]
> This page applies only to engineering apps bought from HD Vision Systems. Runtimes are bought once and need no renewal. For software bought in the ctrlX Store, the LumiScan Key needs no annual update (see [Bought in the ctrlX Store, Running on Windows](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.1/path-ctrlx-windows.html)).

## Checking the expiry date

- **In CodeMeter WebAdmin:**
  1. In CodeMeter Control Center, click **WebAdmin**.
  2. Open **Container > Licenses** and select your LumiScan Key.
  3. The expiry date is shown for each licence.

- **On the command line:** Replace `3-1234567` with the serial number of your LumiScan Key:
  ```bash
  cmu --list-content --serial 3-1234567
  ```

  The entry **Expiration Time** of each licence shows its expiry date.

## Renewing

A renewal requires a valid subscription. HD Vision Systems issues the licence update only while your subscription for the engineering app is active, that is, the annual licence fee for the coming year has been agreed. If your subscription has been cancelled or has ended, contact [licenses@hdvisionsystems.com](mailto:licenses@hdvisionsystems.com) to renew the subscription first.

We recommend starting the renewal about four weeks before the expiry date.

1. [Create a licence request](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.1/requesting-a-licence-update.html) from your LumiScan Key.
2. Send it to [licenses@hdvisionsystems.com](mailto:licenses@hdvisionsystems.com). In the e-mail, state that you want to renew your engineering licences, and give your customer or order number.
3. [Import the licence update](https://docs.hdvisionsystems.com/en/lumiscan-licensing/1.0.1/importing-a-licence-update.html) that you receive from HD Vision Systems.

The renewal is written to the key. You do not need to reinstall the software.

## When the subscription has expired

Without a valid subscription, the engineering app can no longer be used. Your projects and data are not affected. As soon as your subscription is valid again and you have imported the renewal, the app can be used again.
