Windows 7: Canon Pixma MG5450 - NT 4.0 Policy: Driver Issue

Hi,

I bought a MG5450 2 days ago and began setting it up yesterday however stumbled across an issue where the printer driver would not install regardless of the compatibility setting. Being as it's a newly released printer I thought the drivers would be up to date and new, however I think there may be a issue with NT 4.0 driver policy as when I try to install the drivers through the device manager, it gives me that message that there's a policy in place stopping me.

Windows update always fails when trying to install the printer, however the scanner, and software included all work fine. I can scan images on wirelessly and have them saved on my computer without an issue, however there is no way to print.



I have tried disabling the policing through the 'MSC' and adding a local group policy or something along those lines. However none of this has worked. How can I get the driver to install or disable the policy to allow the printer to be installed.

My Printer

Running Windows 7 Ultimate 64x
Tried installation of the drivers both through wireless and wired, both come to the same outcome.

Any other information needed, then please ask.

Thanks!

Windows Update when USB plugged into the computer from the printer.

I have spoken to Canon support through email and they have said this is down to a Window issue.

Does anyone have any experience of installing a Canon printer on Windows 7 where this issue is in place?
