trying to install most current software/driver for HP Photosmart C4750 printer. Software downloads but after successful install the next step is product configuration. During product configuration  I receive "fatal error installation" message. HP error report seems to think I am operating a windows 8 version when in fact I have updated to windows 10 2004 version. I was also told to check firewall software and to make sure UDP port 427 is unblocked. I don't know how to do this. Could either of these issues be the problem the that is causing the "fatal error" message?
