    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:

    (KB972363)
    (KB973709)
    (KB952581)
    (KB974234)
    (KB969907)


    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.

    Validate your copy of MS Office 2007 ... this should help with any future updates.
