Hi,
Not sure you will be able to help as no one on this forum has been able to help. I have the Officejet 4500 (G510n). I have the original disk (for Windows XP or 7), I am running Windows 8 (64 bit). When I download the software from the site it downloads OK and starts installation and then gets a message it is missing a temp file and cannot install, the disk cannot be read by my computer for some reason.
