Are you using a network connection when installing or a usb connection?


If you are using a network connection and receiving this error, please check your print server properites and see if you have any Universal Print Drivers installed. If you do, then you need to uninstall and delete these from your system, re-boot, and try and re-install the m451.


Steps to take:


1. uninstall all failed attemps of the m451 software from your system, reboot.

2. Check Print Server Properties for Universal Print Drivers, uninstall, delete, reboot.

3. Check in your Program Files, under any HP folders for Universal Print Drivers and delete from system, re-boot. (make sure you empty your recycle bin).

4. Download a fresh updated copy of the m451 driver from and try to re-install.

Using a USB connection. Solved the problem myself - uninstalled and re-installed again works fine

Re: HP Laserjet pro 400 Color M451dn

Hello! I am having the same exact problem. I am using USB connection. It extracts the file, prepares to install and tells me to connect the product,it shows that the product has been detected and waiting for product setup to finish. It gets to 99% on this and tells me it took to long. I have tried shutting down and restarting and running again. Every time the same thing. i have done this process at least 6 times.

I would greatly appreciate any help.
