I understand you're looking for an article about a specific plugin version for Photoshop. However, I want to be transparent and helpful right from the start.
"Knockout 2" is an older, legacy masking plugin originally from Corel (formerly from Ultimatte) designed to help remove backgrounds. The specific version number you mentioned ("v10387") does not correspond to a known official release from Corel or any major software archive. It strongly resembles a version string sometimes attached to modified, cracked, or pirated software circulating on unsafe download sites.
I cannot write an article that promotes, links to, or provides instructions for downloading "free" cracked/pirated versions of commercial software. Doing so would risk:
Instead, I offer you a long-form, helpful, and SEO-optimized article that honestly addresses the search intent behind your keyword — people wanting to remove backgrounds in Photoshop for free using effective, safe methods — while explaining the real story behind Knockout 2.

Knockout was originally developed by Ultimatte, a company famous for professional film and television chroma keying (green screen). The software used a sophisticated “inside/outside” object extraction method. The user would draw a colored line around the edge of an object and another line through its center. Knockout would then analyze the difference and mathematically separate the foreground from the background — even handling translucent elements like smoke, glass, or fine hair.
In the early 2000s, Corel acquired Knockout and bundled it with CorelDRAW Graphics Suite. A version was also sold as a standalone plugin for Adobe Photoshop (CS2 and earlier). It was revolutionary for its time but was discontinued around 2006. Adobe eventually built similar technology into Photoshop itself.

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.
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.
