I had a problem with my HP printer not scanning via the wireless network even thought it did in the past. I could print wirelessly. The ADD/REMOVE program wouldn't allow me uninstall it came up with an installation error when trying to do so.I then went onto a HP forum to try and get help and was directed towards deleting the HP files and downloading the HP driver from scratch. Afetr manually deleting the HP folders/files and downloading the relevant full HP driver I now get an installation error when trying to install the printer. I am now at a point that the PC doesn't even recognise the printer on the network and I can't install the driver. Is this something to do with the ADD/REMOVE program not being able to uninstall properly?
