Acrobat 64-bit for Windows Enterprise users

The latest version of Acrobat is now available for enterprises to deploy for Windows 64-bit machines. This article provides details on the Adobe’s Unified app installer, and some important procedures to customize the Adobe installations.

Why deploy Acrobat 64-bit on enterprises?

To streamline installs and simplify app management for large enterprise, Adobe now delivers a 64-bit Acrobat and Reader all-language (MUI) unified installer. Adobe’s single-app initiative provides both Acrobat and Reader functionality via a single installer, a common default install location, and a common executable and registry hive.

Note the following benefits:

  • A single default install path that simplifies product deployment and management:
    C:\Program Files\Adobe\Acrobat DC
  • 64-bit Acrobat supports the easy-to-manage Shared Device Licensing method.
  • Available features are determined by the licensing  or activation credential rather than installing two different products. Users with Acrobat rights get those features on sign-in. Other users get Reader.
  • Two app installs are no longer required.
  • Automatic and managed updates workflows continue unchanged.
