Running Windows 7 Pro (64 bit). Downloaded these files from HP: (1) LJ-M401-drv-installer-13198; (2) LJ-M401-full-solution-13198; (3) LJ-M401dne-full-solution-13067. Each time I ran any of the files, I got about 91% complete at the "preparing to install" stage and then got the error message that the installation encountered an error and I should reboot. I have now rebooted several times and still have not succeeded with installation of any of the files. I have disconnected the USB cable everytime and still none of the files will install.
There must be some kind of workaround but I haven't found it. Any help out there?
