Question

I'm trying to install an mp610 on my dell inspiron computer, to replace an mp600. The installation cd told me that another printer was set to the computer so I deleted everything on the "printers and faxes" but it's still saying the same thing and won't let me continue with the installation. I would be very grateful for some advice. Thanks
