Hi Rahul,


I have the same problem with my new HP Pavilion x360 14-ba103ng, that also doesn't have a physical ethernet port. What address should I request a new license for? And is it still possible to refresh a HW14 license or do I need to do a new registration for HW2017?


KInd Regards

Robert Courant
