I thought it was relevant to the original poster. Many posters fail to
provide sufficient information to assist in the diagnosis of problems.
I asked the OP for some more information, by checking the update history for
failed updates to give more clues. Just saying yo have an error code 646
doesn't mean that much really, does it?
I suggest you contact Microsoft for support issues, visit the International
Support Web site:
To make sure you receive the appropriate support information for your

:: I don't think ou read the post.
:: The error code is 646. I am having the same issue.
