This is a portable version of the software 3D Choreographer, well known for Rapsittie Street Kids. Yeah, that movie!
From Lost Media Wiki:
"3D Choreographer was a 3D animation tool created in 1992 by Animated Communications, Inc, designed to be an animation program for non-artists. It is perhaps most notable for being the software used to animate the infamous Rapsittie Street Kids: Believe in Santa.
3D Choreographer was created in 1992 by Jeffrey Freedman, focused on making a simple and easy to use program for 3D animation.
Initially, The program had two different versions available: The 3D Choreographer CD was a basic package that cost $199 and contained 90 actors, 50 AVI files and animation templates, and the 3D Choreographer Deluxe Version, which contained 330 actors, 60 AVI files and animation templates and cost $349.
In 2005, the Deluxe version was merged with the basic version and was made available for $109 and introduced two new versions of the program, one being 3D Chor Kids, which was intended for grades 2 and up and omitted some of the characters included with the $109 package and 3D Chor Video Effects Studio, a separate program that was more focused on importing images onto heads of characters or using video as a background for characters to interact with human actors.
Multiple versions of 3D Choreographer are known to exist, and were available to be purchased either through Animated Communications' website or from various licensed vendors. However, none of these versions have been backed up online. A non-interactive demo from 1994 was found on a cracked shareware CD-ROM. An installer for the program was included alongside the demo, however is most likely to be corrupt or incomplete, and thus cannot be run.
On 26 July, 2021, Reddit user idiotic_bastard announced in a thread on the /r/lostmedia subreddit that they found the full version of the 3D Choreographer. The user explained that the program was posted on old BBS warez sites. They were able to find BBS sites that still functioned, downloaded them, and uploaded the files to archive.org. Their post also gave instructions on how to get the program to run.
(IMPORTANT) As the program was not made for modern Windows, you need to have the otvdm/winevdm installed on your PC to run it, or you can use on an Windows 3.1/95 DOSBox/VirtualBox/VMWare virtual machine.
