I just tried to install the software for an HP Deskjet 6310 on a client's laptop using the CD that came with the system. The install software said there was already a newer version of the software installed on the system - and doesn't give me any other options. He does have several other HP printers installed so we eventually uninstalled them all to troubleshoot this problem - no change. I then deleted all hp*.* files on his local drive and all temp files - no change. I deleted all references to HP in the register; again, no change.
I manually installed the printer driver so he could at least print - but when he prints, HP tries to install 'market research' software in the middle of the print job, and can't find it on the CD.
Any suggestions? This is driving me nuts.
