H P Deskjet Printer will not install. Error 3

My daughter has a Laptop which has a Windows 10 Pro O/S. It seems to have all the updates. Her printer, which she has had for over a year, is a HP Deskjet 3630 Series. Recently the printer stopped printing from the laptop. I have made several attempts to reinstall the printer with the laptop, using both the original installation disk and the HP printer installation website, all to no avail.

When I attempt to reinstall the printer the following messages pop up at different points in the printer installation process.
1. Installation Error 3: Failed to copy Port Monitor files.
2.: HP DJ3630 Series Printer Driver is not compatible with policy enabled on your computer that blocks NT 4.0
3:Windows can't install the HP Deskjet 3630 Series kernel mode printer driver. To obtain a driver that is compatible with the version of Windows you are running contact the manufacturer.

I can only guess that a recent Windows 10 update has fouled things up but as my daughter prints from Windows very infrequently I have no idea which Windows update might have done the damage. The printer will still scan and it will print from an iPad.

I would be grateful for a solution to this problem.

Ken, the laptop has not been updated to 1809, not yet anyway. From what I read this problem seems to occur often with HP printers.

Find the installer in File Explorer, right-click it and select "Troubleshoot Compatibility".

Hello Ken & Ben,
I live about 200 miles from my daughter. I was with her last week and spent many hours doing uninstalls and re-installs of the printer, following instructions I had read, but got nowhere. I am also corresponding with HP Community Forum and I am receiving similar advice as I am getting here. I shall have to use Team Viewer to take remote control of my daughter's laptop and try out your suggestions. I will report back how I get on but it may be a day or two. Regards, gordon99

Ken, I am relieved to be able to say I have managed to restore the laptop to printer printing facility by following the guidelines from "shomiL" in your link https://h30434.www3.hp.com/t5/Printe...r/td-p/6237925. I fully removed the printer software first before starting mods in the registry files. Having done all of that the reinstall of the printer software was quick and easy. However, when I had completed all of that my daughter complained that her email client (eM Client) had disappeared. I have no idea why that should have happened. The program was missing from C\ Programs though the data files etc. were present in C:\ Users\ xxxxxx. I had to download and install the program and then it was back fully functional.
Thanks very much for your help.
