error code 646

I have been trying to install updates for the following:

Security update for MS Excell KB973593
Security update for 2007 MS Office KB973704
Update for MS Word 2007 KB974561

for at least two weeks now and they will not install. I keep getting error
code 0000646. I had the same issue a few weeks back with other security
updates for office products and after about a month it finally updated. Now
I'm back having the same issues with these new updates. But yet other
updates have installed just fine while these continue to hang out there. I
don't have them already installed either so I don't know what is going on.
If anyone can offer help I would appreciate it.
