Access to Office 2003 from Limited User accounts

[r]

After installing Office Pro 2003 on my machine from an admin account the
limited accounts can't access the Office applications correctly. The icons
are available in Start - Programs - Microsoft Office but when they're clicked
a pop-up comes up and
says that Office is being installed. After a time the application will come
up but then goes through the same hoo-ha when the app exits. This happens
every time an Office application is started. All this disappears if I grant
the account admin status. OS is XP Pro. If there a way around this? I have
looked at the document "Configuring Support for Multi-User Computers and
Traveling Users" but it wasn't clear to me exactly what I needed to do to
resolve the issue. I'm not very experienced with this kind of computer work.

Thank you.
