Grant only to local administrator ability to install outlook

Hi,


I would like to grant only the local administrator (not the group administrators) the ability to install outlook.
I would like to prevent users that are local administrators to install only MS Outlook on their computers.
how is it possible?
i thought of maybe make a folder where outlook is being installed and give permissions there, or at the registry navigate to where the container (?) of MS outlook and give the permissions there...


any ideas / suggestions?
