Hp 2055dn Driver Windows 7 64 Bit

Hp 64 Bit Driver

I had to re-install Windows 7 OS along with everything else on my desktop. Before that, the laserjet printer was up and running fine. Now, I am using the cd that came with the printer in hopes of re-installing the software.
How to install the HP LaserJet P2035n in a network environment with Windows 7 (32 and 64 bit) using the PCL5 HP. Double click on the downloaded UPD PCL5 driver. Microsoft Windows 7 (64-bit). Re-install software for laserjet 2055dn for Windows 7. Installing and Using the Windows Built-in Print Driver; HP Printers.
But the install stops with two messages: I am not the administrator (BUT I AM and the only user on the pc) and second, the operating system on this computer does not match the supported operating system; it lists every OS before Windows 7. It seems that the software pre-dated Windows 7. There must be an update to download.So: I searched the downloads for HP and am only confused. I see driver updates but that is not what I need.????
