You're looking for information on the Knockout 2 plugin for Photoshop, specifically version 10.387, and possibly a free download. Here's what I found:
What is Knockout 2?
Knockout 2 is a plugin for Adobe Photoshop that allows users to easily remove backgrounds from images and create transparent PNGs. It's a popular tool among designers, marketers, and e-commerce professionals who need to quickly and accurately remove backgrounds from product images, logos, and other graphics.
Version 10.387
The version number you mentioned (10.387) suggests that you're looking for a relatively recent update of the plugin. However, I couldn't find any official release notes or announcements from the plugin's developer (Redynamo) about this specific version.
Free Download?
As for a free download, I couldn't find any reliable sources offering Knockout 2 v10.387 for free. The plugin is commercial software, and it's unlikely that you'll find a legitimate free download. Be cautious when searching for free software downloads, as they may be bundled with malware or other unwanted programs. knockout 2 v10387 plugin photoshop free new

Knockout 2 was a standalone masking application that also functioned as a plugin for Adobe Photoshop (CS2, CS3, CS4, and early CS5 on 32-bit systems). Its core technology used a “tri-map” approach:
By analyzing color differences, Knockout 2 excelled where standard channels and background erasers failed: wispy hair against complex backgrounds, smoke, water droplets, and translucent fabrics. Redynamo Website : You can visit the official
The interface was deceptively simple: load an image in the Knockout 2 workspace, paint the keep/remove regions, and hit “Process.” The plugin would return a perfectly masked image to Photoshop with a transparent background.
You could create a similar plugin using Photoshop’s UXP/CEP + AI background matting. Here’s a pseudo-code concept:
// Photoshop ExtendScript (modern equivalent of Knockout)
var doc = app.activeDocument;
var originalSelection = doc.selection;
// Use AI-based background removal
app.activeDocument.activeLayer = app.activeDocument.backgroundLayer;
app.activeDocument.selection.selectAll();
// Run "Remove Background" AI action
var desc = new ActionDescriptor();
desc.putString( stringIDToTypeID( "algorithm" ), "background" );
executeAction( stringIDToTypeID( "removeBackground" ), desc, DialogModes.NO );
But that requires Adobe’s AI engine – not a standalone plugin.
The v10387 build is significant because it represents the version optimized for compatibility with newer Windows architecture while retaining the original Corel processing engine.
No. Knockout 2 was commercial software, priced around $150–$200. Corel discontinued it around 2008–2009. Even though it’s abandonware (no longer sold or supported), copyright law still applies. Downloading it from torrent sites, file-hosting boards, or “free serial” blogs is piracy.
Exception: If you own an original CD or a valid license key from Corel, you can continue to use it under the original EULA. Some users archive their own copies. However, distributing it remains illegal.
