Hi I have just installed Office 2000 on some machines in our
training room - all the other applications in Office work fine, but
Outlook doesn't open -- it just crashes as the opening window is
appearing.

We have three other versions of Office on these machines - 97, 2002
and 2003. The operating system is Windows XP Home edition.


You have 3 (now maybe 4) versions of MS Office installed within the
same instance of Windows? You don't run into problems with the same
registry settings being used by multiple versions of the same program?
Are you using SVS from Altiris (acquired by Symantec) to load only one
copy of whichever version of MS Office you want "installed" at any
time, or running them in VMs?

Read the paragraph starting with "You cannot run multiple versions of
Outlook on the same computer."

And the paragraphs starting with "Microsoft Office Outlook 2003 cannot
coexist with any earlier version of Microsoft Outlook."
