For a 64-bit installation of Adobe Acrobat on Windows, the plugin directory is typically:

• Windows (64-bit Acrobat on 64-bit OS): /Program Files/Adobe/Acrobat DC/Acrobat/plugins or /Program Files/Adobe/Acrobat [Version]/Acrobat/plugins
• For 64-bit versions of Windows, this might be under /Program Files (x86)/Adobe/Acrobat [Version]/Acrobat/plugins if you’re running a 32-bit version of Acrobat on a 64-bit version of Windows.

On macOS, the application structure remains consistent regardless of the processor architecture, so you can find the plugins directory at:

• macOS: /Applications/Adobe Acrobat [Version]/Adobe Acrobat Pro.app/Contents/Plug-ins

In these paths, [Version] should be replaced with the version number of Adobe Acrobat you’re using, such as DC, 2020, etc.
