Uninstall Flash and Upgrade Adobe Acrobat

Remove discontinued Flash Player components from your system and upgrade to a modern version of Acrobat to process PDF responses safely.

Adobe Flash Player reached its end of life and is no longer supported by Adobe or modern web browsers. Legacy PDF forms that rely on Flash for dynamic content or data extraction can no longer function in their current state and must be migrated to modern standards.

1
Uninstall Adobe Flash Player

Navigate to your system's Control Panel or Settings app, select 'Apps & Features' (or 'Programs and Features'), locate Adobe Flash Player, and click 'Uninstall' to remove it completely.

2
Upgrade your PDF software

Download and install a modern PDF application, such as Adobe Acrobat Pro DC or Acrobat Pro 2020, which utilizes secure HTML5 and JavaScript instead of legacy plugins.

3
Process the PDF responses

Launch your updated Acrobat application, go to 'File' > 'Open', and select your legacy PDF response files. You will now be able to view and extract the data without the Flash Player prompt.
