Unknown errors 643 and 646 when updating Vista 32

Hello, just recently I haven't been able to update vista, I keep getting unknown errors. I look at the updates that failed and they are as follows. What can I do to fix this? Thanks!

Ok, I tried the "Fix It" the regular way and the aggressive way and I'm still getting the two error codes. Any other ideas? Thanks!

Try this:
Windows Update - Reset - Windows 7 Forums

Try installing one update at a time
Try with anti Virus turned off
If it just started use system restore to go back to when it was working and then install one at a time. One at a time is always good advice, due to potential conflicts when the computer has to be turned off to complete an update.
Try in safe mode.

Worthy of Rep, but I have to wait before I give you more. But in any event, job well done.
