Hello, the Office 2003 Updates of March 2010 for Excel KB978474 + Outlook KB979771 won't install. Seems I'm not the only one to whom that happens. No suggestions I found helped. The updates simply say the installation failed. KB949074 was NOT installed, so I tried THAT first - fails too. Common to all is that installation trundles endlessly, until it finally says it would be preparing - only to fail a few seconds later. I'm completely clueless.
