Installing an add-on works exactly the same way as any other plugin within WordPress. To install an add-on, please do the following:

1. Download the file from your original purchase receipt. If the link has expired, don’t worry, you can download it again from Your Account.
2. Go to Plugins > Add New in your WP Admin.
3. Click Upload Plugin at the top of the screen.
4. Choose the file from your computer that you downloaded in step 1 and click Install Now.
5. Once installed, activate the plugin.
6. Proceed to add and activate your license key.
