# Pro Activation

> Install the Pro plugin and activate your license key.

After purchasing Pro, Freemius sends the plugin download link and license key by email.

If you bought a monthly or annual license, you usually receive two emails:

| Email          | Contains                                   |
| -------------- | ------------------------------------------ |
| Download email | Pro plugin ZIP file and license key.       |
| Receipt email  | Payment receipt and invoice download link. |

Lifetime purchases may arrive as one email that includes the download link, license key, receipt, and invoice.

## Download the Pro ZIP file

1. Open the purchase email.
2. Download the Pro plugin ZIP file.
3. Keep the license key available. You will need it after activation.

Do not unzip the file before uploading it to WordPress.

2. Go to **Plugins > Add New**.

If you upgraded from inside WordPress, the license may already be activated.

If the activation screen appears:

After activation, the licensed plugin options become available in the plugin settings.
