Current Adobe pro x65 package is not unified and prompts for sign in. New Adobe Pro unified x64 package helps to create a single package for a customer (deployed with customization to remove prompt for sign-in) makes it possible for a customer to deploy a single package for all users that works as Adobe Acrobat reader x64 if user dont have any Acrobat Pro or Acrobat Std license and works as Acrobat Pro or Std once user signs in to Adobe from the application depending on which license he has.
Note - Single unified package works as Acrobat Pro or Std or Reader (just remove sign in prompt using Adobe customization tool and deploy & deploy with MST).
My company is looking for an Adobe Acrobat Pro installation. We no longer have Adobe Acrobat DC but it is the only thing still listed under updates.
