Vista - Error Installing Printer Driver

I just bought a new desktop loaded with Vista x64 SP1. I am having trouble getting my Canon ImageClass D300 printer driver to install. I've been through the forums and such here and have tried all the take ownership of the files, run as administrator, login as administrator and all the disable the signed driver stuff and I'm still getting this error:

Windows found driver software for your device but encountered an error while attempting to install it.

Then it displayes the printer and correct name. Below that is simply says:

Access denied.

I'm at my whits end here folks. If someone can direct me to what the access might be that's denied, i'd love to take alook at that. Like I've said, I took ownership of the entire drive so I was sure to get everything. I even tried the same take ownership of all I could in the registry. Any help would be great.

I guess I should have held off on posting here, that's always my luck. At any rate, I was able to sort of figure out what was going on here. Since the computer came with a restore partition and nothing was working and I had very little setup, I figured I had nothing to loose, so I ran through the system restore and put it back to whatever their factory specifics were. After that everything the printer driver installed without issues. So who knows what happened to the initial load, but it was bad.

So like I tell my wife, when in doubt reboot. Or in this case, reload.
