Thanks Microsoft for adding more bugs with software that benifits you. I can't estimate how much of my life you have stolen with your poor quality and terrible error handling.
Microsoft is famious for errors like "A program has an error and must be terminated", or "A file is in use by another user".
Another faviorate, updates which just announce a status of "failed". How about some clues?
Can you walk us through your scenario?
You seem to either be having permissions issues with your system or something of the sort.
I would suggest walking through www.microsoft.com/genuine/diag
