2. Once available, transfer the **zip/compressed** license file to a USB 3.0 compatible storage device.
3. Plug in the USB 3.0 storage device into the **blue USB 3.0 port** on the left side of the instrument.
4. Login to the Control Software as an **Administrator** user account.
5. Within the Control Software, use the **External Storage** user interface (UI) to add the USB storage device.

6. From the **Settings** menu, select **DRAGEN**, then select the **License** tab.
7. Select **Update from file**, then select **From external storage**.
8. Navigate to the zip/compressed license file on the USB 3.0 storage device.

    1. If there are any issues with installing the license file, select **Download log** and contact [Illumina Tech Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support).
11. Select the **Versions** tab.
