Outlook 2003 not starting - Windows 7 x64

Recently upgraded my OS to Windows 7 x64(64 bit) Ultimate Edition. Then installed full version MS Office 2003.

All Office 2003 started up successfully except for Outlook.

During the start up phase for Outlook 2003, Windows 7 will prompt and complain that the application is not responding and did not start correctly. Tried running Outlook 2003 as Administrator - failed.

Solution

Installed MS Office Service Pack 3, restarted my computer.

Outlook 2003 worked like a charm.
