I installed Office 2003 on brand new Windows 7 x64 a few eeks ago.
No problems installing, no problems transferring all data from old system,
never any problem opening Outlook, or any other office apps.
Everything (Windows, Office ) at the latest update SP and release.
Outlook regulary stops working, and restarts. Quite often when starting a
new email.
I have removed all add ins.
Often Outlook will also not close - when using the "X" at the top Right
hand
corner. When this happens it can only be closed using file exit.
Never ever had any of these issues when running on XP
