Installing CartPops
Install CartPops Free from WordPress.org, or install CartPops Pro from a ZIP file and activate your license.
CartPops needs WooCommerce, so install and activate WooCommerce first. See the requirements for supported versions.
Install the Free plugin
Open Add Plugins
In your WordPress dashboard, go to Plugins and click Add New.

Search for CartPops
Search for CartPops. It should be the first result.

Install and activate
Click Install Now. When it finishes, click Activate.

CartPops is now active. Continue with First-time setup.
Install the Pro plugin
Download the Pro ZIP file
After you buy CartPops Pro, you receive an email with your license key and a download link. Download the .zip file from that email. You can also download it from your account.
Deactivate the Free plugin
If CartPops Free is active, go to Plugins > Installed Plugins and deactivate it first. Your CartPops settings are kept when you deactivate or delete a plugin.
Upload the plugin
Go to Plugins > Add New and click Upload Plugin. Choose the CartPops Pro .zip file, click Install Now, then click Activate.

Activate your license
After activation, CartPops asks for your license key through the Freemius activation screen. Paste the key from your purchase email and click Agree & Activate License.
Freemius is the licensing and update service CartPops uses. The plugin contacts it to verify your license and to check for updates.
Delete the Free plugin
Once Pro works, you can delete the deactivated Free plugin from Plugins > Installed Plugins.
CartPops Pro is now installed. Continue with First-time setup.
Switching between Free and Pro
To move from Free to Pro, follow the Pro steps above. To move from Pro back to Free, deactivate Pro first, then install and activate Free from WordPress.org. Deactivating or deleting CartPops keeps your settings, analytics and licensing records. Permanent data removal is a separate, deliberate action, so deleting the plugin does not reset your data.
If your Pro license is not available, for example because it expired, Pro features pause but your saved Pro settings are kept.
Upgrading from V1
If CartPops V1 is already on your site, do not follow this page. Read Upgrading to V2 first.
