Pushing non microsoft updates to users

Hello,



I'm a new server administrator using Windows server 2003....
I am trying to come up with a way to push Adobe acrobat Reader 7.0.7
too all our users all of which are "Power Users" but not
administrators even on their local machines. Those default rights
prevent them from installing updates themselves.
What I need to do is push or (create a logon script) that pushes
the update to them when they log in.
How do I do that since they can't install software with their login
permissions? I know they can accept the "Windows Updates" and
install them as themselves.....I've done a ton of research but
obviously not in the right places yet.

All help will be MOST appreciated !!!
