Maybe you forgot to click on "Confirm...?"
Have you tried a different USB cable?
Did you check the current volatges in your bios Setup? - +5v must be within 10% of it's nominal value.
HP used to have a HP software cleanup utility, at least it did a couple of years ago - it is supposed to remove everything to do with all HP software - but I don't know if it's still there. You could try searching for that.
If you don't find that, or if you do and it doesn't help.....
If the software is installed by Windows Installer, which is the case for a lot of more recent software, you could try this.
Go to the Microsoft web site and find the "Windows Installer Cleanup Utility", download it, and install it.
You could install the software as far as it will go - in most cases you leave the USB cable unplugged until you are prompted to insert it - or if the software is already there....
Run the Windows Installer Cleanup program, find the listing for the HP printer software, and delete the entry. At the very least that is supposed to de-activate anything active to do with the software, by using the original Windows Installer information - it removes the entry(ies) for the software in Add/Remove Priograms - it may even remove the files originally installed.
Then reboot and try installing the software again - in most cases you leave the USB cable unplugged until you are prompted to insert it - the printer's power probably must be on when you plug in the USB cable, even if it can turn on automatically once the software has been installed.
"when I try to install again via Add Printer, in the wizard it says a driver is already installed for the printer and I have to option to replace or use the existing one. "
If Windows keeps finding the printer drivers automatically after you have un-installed it's software, obviously uninstalling the HP software and using CCleaner didn't remove the *.inf file(s) for the drivers, and possibly the driver files.
- delete the printer in Control Panel if it is still there after you un-install the HP software, if you haven't already done so.
- you may need to delete the *.inf file(s) for your model. Search for *.inf files containing your printer model number, or the model series number - look at the ones you find - the date of it may be a clue - confirm that it applies to your printer before you delete it - if you not sure, copy it(them) to someplace other than in the Windows folder, delete the *.inf file in Windows.

Of course, but if you don't, how is anyone supposed to know you even read the responses?
