[Urgent] Office 2000 'WarnOnNonAdminInstall' issue - Group policy patch?

Skip to the last line if you don't want to read what I've tried already...


This is for a public room booking venue, I want all the applications to be as easy to use as possible - a lot of "Windows/Office for dummies" classes are run here.

I'm upgrading one of the computer labs from NOT w/NT4 DC, configured with the old policy editor, to Win2kP clients, Win2kAS DC/fileserver.

I've configured user profile customisations via group policies, and the only issue I'm having now is when office applications are run, the "Install Program As Other User" dialog pops up, presenting the user with the options:
----------------------------------------------------------
* Run the program as MMLAB\<user>
* Run the program as the following user:
    ? User name: |Administrator|
    ? Password: |<blank>|
    ? Domain: |<blank>|
[ ] Always run install programs as MMLAB\<user>
----------------------------------------------------------

Running as the current user is sufficient for the installer to do... whatever it is that it wants to do, so no elevation of privileges is needed.

Ticking the box "Always run install..." sets the registry value:
----------------------------------------------------------
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain]
"WarnOnNonAdminInstall"="no"
----------------------------------------------------------

But this is, of course, on a user-by-user basis. I want to stop this dialog from popping up altogether.

I've written plenty of ADM's for the old-school policy editor, and never had any issues setting any values, anywhere in the registry... but writing up an ADM for the new GPEditor /seems/ to only allow writing values to:
----------------------------------------------------------
CU\Software\Policies
CU\Software\Microsoft\Windows\CurrentVersion\Policies
LM\Software\Policies
LM\Software\Microsoft\Windows\CurrentVersion\Policies
----------------------------------------------------------

I might be wrong in this (but it's what the MS doc says - http://www.microsoft.com/windows2000/docs/rbppaper.doc [page 12]).

When I create a ADM to manipulate the specific key, the policy doesn't show up in the editor, but writing to:
----------------------------------------------------------
CU\Software\Policies\Explorer\DontShowMeThisDialogAgain
CU\Software\Policies\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain
CU\Software\Policies\Microsoft\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain
CU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DontShowMeThisDialogAgain
CU\Software\Microsoft\Windows\CurrentVersion\Policies\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain
CU\Software\Microsoft\Windows\CurrentVersion\Policies\Microsoft\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain
----------------------------------------------------------

Don't prevent the dialog from popping up.

So here's my question:

How do I stop the "Install Program As Other User" dialog from popping up?
