Cant uninstall old HP Printer

Is there more to the message such as "try an alternate path" or something else? It may not be finding a file it needs to uninstall the program. You can try this link (scroll down to the resolution section): http://support.microsoft.com/kb/2438651
The better bet may be to try an uninstaller from HP: http://h10025.www1.hp.com/ewfrf/wc/searchResults?tmp_qt...
