Code 646: Issues with Windows 7 updates failing

I recently ugrade from Widows 7 Ultimate editin from Windows Vista Ultimate edition recently, but I began having update issues with it almost immediately.

I'm seeing the following (Office 2007) updates continually fail, each time I use the update service. The updates successfully download, but fail to install. I have managed to manually install some of them, but the few I have listed below, I am simply unable to install successfully. The following is a list of the updates, which appear to be hung, with no resolution in sight.

Code 646:


Can anyone help with this issue? I've tried everything and "Microsoft has no support for Windows 7 issues at this time." I'm stuck with security gaps here.
