Good morning! I am trying to install a HP OfficeJet 4500 G510-n printer on a computer. The OS is Windows 7 32-bit, the printer is hooked to the computer through a USB cable. I do the installation (either with the CD included or the file from their website), it runs smoothly until the end where I get a Fatal Error, and then it uninstalls itself. The details of the error talk about some registry entries, I guess it can't write into the registry. I tried having Windows detect and install the printer by itself, it works but it only installs the scanner, not the printer. Any idea??? Thanks!!!
