Ronnie: I havethe Office Service Pack, but still get this Powerpoint 2007 critical update error. I may have to avail myself of the email support link that you suggested. I dread asking MS for service as a lowly sole-user! Adam

Hi Adam No need to 'dread' asking. They provide very good support for the security updates. Every Windows user is very important to MS. Ronnie Vernon Microsoft MVP Windows Desktop Experience

I am getting the error code 80070643 and the links to the KB articles are not helping. I am running Windows 7 with office 2010, so why is update trying to patch something that I have already upgraded?
