From End of Life (EOL) for Adobe Shockwave:
Companies with existing Enterprise licenses for Adobe Shockwave continue to receive support until the end of their current contracts.
Adobe Shockwave is a browser-based multimedia platform for interactive applications and video games. Retiring the Shockwave player for Windows is the last step in a multi-year process: Adobe Director, an authoring tool for Shockwave content, was discontinued on February 1, 2017 and the Shockwave player for macOS was discontinued on March 1, 2017.
Adobe continues to offer a rich set of content creation tools through Creative Cloud, including Adobe Animate for authoring interactive content for multiple platforms, such HTML5 Canvas, WebGL, Flash/Adobe AIR, and others.
