Does this show a message "Plugin could not be activated because it triggered a fatal error." prior to your output?

hi,
you can check if another plugin is installed with this method is_plugin_active.
In your example, we have something like this
``
/**

• Activation Class
  /
  if ( ! class_exists( 'WC_CPInstallCheck' ) ) {
  class WC_CPInstallCheck {
  static function install() {
  /
  * Check if WooCommerce & Cubepoints are active
  **/
  if ( !is_plugin_active('woocommerce/woocommerce.php'))
  // Deactivate the plugin
  deactivate_plugins(FILE);

        // Throw an error in the wordpress admin console
        $error_message = __('This plugin requires <a href="http://wordpress.org/extend/plugins/woocommerce/">WooCommerce</a> &amp; <a href="http://wordpress.org/extend/plugins/cubepoints/">Cubepoints</a> plugins to be active!', 'woocommerce');
        die($error_message);
    }
}

}
}

register_activation_hook( FILE, array('WC_CPInstallCheck', 'install') );
``

it also shows error
