The installer of Adobe Reader is smart and removes any previous version 
by default, so no need to take care of this.

I would just create a simple check for the version of the uninstall 
registry key.

I would assign a Adobe Reader remove package to those systems, that are 
not meant to have Adobe Reader installed.

Attached find my Adobe Reader package, password "wpkg" to keep the AV 
software from lurking.
