I've just set up a new home wireless network on my dell laptop and I would like to wirelessly connect my printer again. When the installer detects the printer, the installation program freezes and I get the message HP Installer UI Plug is not responding. I have Windows 7, an HP Photosmart c4780 printer and run MacAfee security. Any help would be appreciated.

Try by temporarily disabling McAfee. If you can install it, then you can re-enable McAfee security.

Right now I'm reconfiguring the printer in the HP configure a network device. It's been running(reconfiguring) for a while. Should I start the USB to wireless over again after the firewall is turned off, or will it work mid-configuration?
