Re: HP Device Toolbox software Error Unable to connect to the printer

Hello tf22raptor.

I see that you're now experiencing an issue getting the Device Tool box to run. I will try and assist with this.

After reviewing this post and the other thread, I have a few things you can try.

1) Run MS Fix it utility to uninstall the software: Fix problems that programs cannot be installed or uninstalled.
(This is to make sure the software is completely removed and conflicts in the registry get resolved)

2)Msconfig: press windows key and R on the keyboard> in run box type "msconfig"> on window select "services tab"> check box next to "hide all MS services> press disable all> go to "startup" tab> press disable all> press apply and ok at the bottom> this should prompt a PC restart.
Please restart.

3) Re-install via USB

4) Try running the device toolbox now

5)If still having issues installing wireless, you may have to contact the router manufacture.

I hope this helps you out. Thanks for posting on the HP Forums.
