The Windows Installer service allows for automated software deployment with
Active Directory Group Policy. In short: Software (MSI Packages) can be assigned
(installed on reboot of a computer) of published (a non-administrative user can
add the software him/herself via Add or Remove Programs from the Control Panel).
More details on this can be found a.o. in the Office Deployment Guide from the
Microsoft Office Resource Kit
(http://office.microsoft.com/en-gb/assistance/HA011402011033.aspx).

If software is published to a user, and the user chooses to install the software
(from Control Panel -> Add or Remove Programs -> Add New Programs -> Add
Programs from your Network) the the user does not need administrative privileges
to install the software. The Windows Installer service will in this case install
the software with 'elevated privileges' (as if the user were an administrator).

However the OOo 2.0 beta installer checks if the user has administrator
permissions, and if not it will generate an error message:

OpenOffice.org 1.9.79 Installerinformationen
The Installation Wizard cannot be run properly because you are logged in as a
user without sufficient administrator rights for this system.

So the installation, which should run without problems, fails. This seriously
hinders OOo deployment in our environment (and possibly a lot of others).

The check for administrator permissions is either not adequate or it shouldn't
be there in the first place.

To reproduce the error you need to have a working Active Directory environment:

1) In Active Directory Users and Computers, create a Organizational Unit (for
testing)
2) In this OU, create a test user
3) Unzip OOo and run msiexec /a openofficeorg1979.msi. Put the installation
(Administrative Installation Point) on a share where the test user has read
permissions.
4) Right-click the OU created in step 1 and open the properties. Activate the
Group Policy tab.
5) Create a new group policy object and double click to modify the new policy object
6) Navigate to User Configuration -> Software Settings -> Software Installation,
right click and Choose New Package...
7) Browse to the share from step 3 and double click the OOo MSI.
8) Choose Published and check that OOo apears in the list.
9) Close the Group Policy Editor
10) Log on to a workstation in the domain as the user created in step 2.
11) Open the Control Panel -> Add or Remove Programs -> Add New Programs.
12) Select OOo from the list of available software from the network and click 'Add' 

If the user is not an administrator, the error will appear.

Please let me know if I can help any further.

Thanks!
