Set default Acrobat (DC versus X pro for specific users) in Microsoft RDS environment

Hello,

I have a single server Microsoft Windows Server 2016 RDS environment. (So a single remote desktop server).

I have Adobe Acrobat X professional for some users.

I have Adobe Acrobat DC for standard users.

The Acrobat X pro users are the only ones able to open the Acrobat X pro software (NTFS rights).

The problem is that all users on the server by default have Acrobat DC open pdf files. And the Acrobat X pro users would like Acrobat X pro te be the default program to open PDF's.

How can I make sure that specific users on the server open Acrobat X pro, and not the free Acrobat when double clicking a PDF file?
