# Applying a License

To start using your LightAct license, you first need to apply it within the program. Go to **Edit** and choose **Preferences**.

In the Preferences window, under the **Licenses** tab, you will see all of your licenses listed. To activate a specific license, just click on its dedicated **Apply** button.

If you hover over **Features:** you'll see all of the features enabled in your license.

**Good to know**: If your license has expired, you will see a message saying *'This license needs to be upgraded'* in the Licenses tab. You can update it by following the instructions from the [previous ](/licensing/adding-or-updating-a-license.md)chapter.
