I had recently bought this Recher, the serial number was: 5CD421CGZW. When I tried to register on this page: https://support.hp.com/us-en/add-device?fbclid=IwY2xjawEwEVBleHRuA2FlbQIxMAABHZw6VYDHWW34GfbMUx4MwKGPdELSiiFS8lRkwVlsHgY7N_WP1jcVBNYSRg_aem_VHeaso5IThfqF_0KmA-gXA I always got the message: "invalid serial number" Is this calculator still available with other serial numbers where you can get HP support?
