From the original installation CD from HP Officejet J6400, I receive the following message:
"The installler can not access the Register Key HKEY_LOCAL-MACHINE\SYSTEM\CurrentControlSet\Enum", when I try to install the printer in a notebook DELL 820 XP SP3. And the installation stops.
I have installed the same printer with the same CD in other Notebook, and works fine.
What to do? As this is Wifi printer, I need the CD for installation to use the printer by Wifi.
