Problem installing Outlook 2003 from assigned package in GPO

[Me]

I'm pushing out Office 2003 (with outlook) in a GPO as an assignment
to desktops. It appears to install fine, but on some systems, when a
user tries to start Outlook, they receive the following errors:

failed. The resource
'HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\UserData'
does not exist.

---------------------------

This is on Win2000 pro. The user's do not have admin rights on the
workstations (however, the error goes away if I give them local admin
rights temporarily). I know that this is a permission problem, but I
don't know on what directory/file/registry key.

Any help is appreciated.
