Thought I would check for updates to my Office 2004 apps and found a bunch. When I tried to run the first one it said Entourage was open, apparently it was started but hanging before anything happened on screen (before the splash screen). After force quitting I ran a few more updaters before trying to launch the app. Not sure if any of them made a difference, but Entourage is working again.
Anyone at Microsoft ever heard of combining the updaters. I had about 20 to do, most for security issues it looked like, and had to do them one at a time.
