Temporary elevation of user rights to install software

I suppose this could turn into a multi-faceted post, but I will be as brief about it as possible.

I wish to create an installer that temporarily elevates user right so a restricted user may perform the installation. There are a few twists along the way. The OS is Windows2000, however it is run in a virtual environment using VMWare Ace.

Short of using something like Wise solutions, is there away to take an *.EXE, let’s use the free Adobe Reader for example, and make it simple for a restricted user to install it?

I fear that manually creating the installer is going to be my only route, but I am up for suggestions.
