How to open old PDFs that used Flash?!

[Melio123]

I have a lot of PDFs and PDF portfolios of ads from way back and can't open any of them. Tried dragging into the updated PDF icon, no luck. Tried renaming and saving. No luck. 

What is ADOBE doing to help us access our work?

Hi Melio,

Hope you are doing well and sorry for the trouble.  Adobe has ended support for Flash Player at the end of 2020 and encourages content creators to migrate any existing Flash content to new open formats, such as HTML5, WebGL, and WebAssembly.

Hi Melio, Flash playback has been disabled by default in Acrobat due to Flash being EOL. However, you can enable the functionality by setting the following registry:

Registry location for Reader:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Reader\DC\FeatureState]
"ADC4318556"=dword:00000001

Registry location for Acrobat:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\FeatureState]
"ADC4318556"=dword:00000001
