Notoriously difficult to uninsatll/ reinstall.
You need to do an L3 uninstall, and reinstall from scratch.
The normal HP/control panel/commercial uninstallers will leave too much behind.
Google L3 uninstall and go from there - it's not difficult, you just need to find the necessary exe file which HP buries deep in the entrails of the system.
Google responses will help you find it.
