Lord, this problem comes up so dang often. We have had this problem, and variations of it, on a number of computers running XP and Office 2000/2002. We have tried all the variations: installing as local admin hasn't worked yet without requiring a reinstall when the domain users logon. And that is the beach of it, because we can't run around to every machine that is used by a new user just to reinstall Outlook and setup new profiles -- it's a huge time expenditure.
We are having better luck installing Office as domain admins, but in one particular case it is not REGISTERING a complete install. But, when I use add/remove features and expand the choices they all show as being installed! I have tried using Microsoft tool MSICUU2.exe which is a cleanup tool, but it does not show any evidence of leftover installs.
HELP HELP HELP!
It seems to me this happens more frequently when Office is upgraded AND windows is upgraded too. It seems like a registry problem that we just can't get undone.
