I have been trying to install the full solution hp 1522 printer software on several computers running "windows vista". The installation didn't install correctly so I wanted to reinstall it, you have to uninstall the HP software thats already installed their. I run the software and click uninstall it runs,finishes. I try and rerun the software and its saying the software is still, so this I click select parts to uninstall and it shows nothing left. Everytime I try and run the software it tells me I have to uninstall the old software first. Any help is appreciated I need this scanning software installed on 5 or so computers all having the same problem.
