Is the native Acrobat C++ SDK still available for download in 2026?

Hello,

I'm developing a native C++ plug-in for Adobe Acrobat Standard 2020 Classic (20.5.30838, Windows x86).

The official SDK documentation still describes native plug-in development, but the Adobe Developer Console no longer lists the Acrobat SDK under Downloads.

I'm specifically looking for Acrobat_DC_SDK_Windows_2021_v3, including the Win32 Starter sample and header files.

Has Adobe discontinued public distribution of this SDK, or is there a new official download location?

Are developers now expected to use a different development environment?

Thank you.
