As per the description above, you want to install Acrobat Pro DC on user's machine which doesn't have admin rights to install any software, Is that correct?
The recommended procedure is that the user's machine should have admin rights for installation and update of Adobe software(Acrobat). However, as you mentioned that the users are in a managed environment, you can Deploy Acrobat Pro DC using the Creative Cloud Packager.
