That message is directly related to the networking device. The first thing to do is to go to Device Manager (Start > Run > devmgmt.msc). Locate the problematic device and uninstall it then access HP Support page and download the necessary driver for your network card. Re-install the driver and then start WiFi Hotspot again and it should work. If I am right, re-installing the driver will fix this issue allowing you to create the required hotspot.
