Microsoft Office 2007,Installation Failure,Error Code: 0x80070643, please help,again?

Question

I'm running a windows xp pro home desktop pc computer, with microsoft office Professional 2007, and I get the following error messages when trying to install critical updates:
Security Update for Microsoft Office Outlook 2007 (KB972363)
Security Update for the 2007 Microsoft Office System (KB974234)
Update for Microsoft Office Outlook 2007 Junk Email Filter (KB974810)
Security Update for the 2007 Microsoft Office System (KB972581)
Security Update for Microsoft Office Visio Viewer 2007 (KB973709)
Has anyone else experienced the same error messages? Is there a way to fix it? If so, how?
The current Office 2007 Pro version has service pack 2 installed. I wonder, are the latest critical updates even necessary to install? or should I just ignore them?

Answer 2

Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free: http://www.pcboostcleaner.com



It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.
