New HP ENVY 5546 Driver Unavailable

[andyrossitter]

I have purchased a brand new Envy 5546 and it will not connect to my PC so that I can print from it. It is connected to my wifi network and shows in my printers in windows but has a message showing driver unavailable, I have tried to connect via the included printer to usb cable and the printer shows that thereis an app associated but when I go into HP Smart it shows that the printer is detected but not completely installed on my windows system. I have uninstalled and reinstalled the software twice but still have the same issue, if I try and update driver via device manager it comes back with an error that policy is in place stopping nt 4.0 files being applied. I recently had an ENVY 5540 which was working fine but is also displaying these errors.

I can print via my mobile phone wirelessly
