Solution 1Recommended

Purchase a New Adobe Acrobat DC Subscription

Since Acrobat 9 Pro is too old to qualify for upgrade pricing, purchasing a new Acrobat DC subscription is the recommended path to ensure full compatibility with modern operating systems.

The historical upgrade path from Acrobat 9 to versions 10 or 11 officially ended in 2015. Serial numbers from version 9 no longer qualify for any discounted upgrade pricing.

Download the Creative Cloud desktop app or the standalone Acrobat DC installer to set up the software on your current system.
