Issue:

Adobe's unified installer is currently taking 2.53 diskspace and not suitable for adobe reader users. We are wasting the disk space there. So, we need a new unified installer where it can act as reader with less disk space and can upgrade into Acrobat pro once the license is allocated to user. All those premium features should get installed on top of this unified package based on license.
This helps on using the disk space efficiently.

I think this is practically possible and will be more use full for all organizations

Single unified package :

Should act as adobe reader and should not consume large diskspace like acrobat pro

Once license allocated , this unified installer should install all the premium features from Adobe and convert into acrobat pro in few minutes.

Also the same unified installer can be released as a Acrobat pro final version where it should act as Acrobat pro itself for licensed people.
