I have tried to install software for HP PSC 1510 all in one printer. I can download the software, but when I install it HP says I already have a newer version installed. I have searched everywhere, can't find the program anywhere! How can I find and uninstall the program that a "ghost in the night" has installed on my pc ? I HAVE LOOKED EVERYWHERE!!!!!!
Go to Start button\Control Panel\Management Tools\Services... and see if the Printer Spooler Service is enabled. If the service is disabled, the software will not appear to be installed, no matter how may times you try.
