As mentioned in other documents, the Kaleidoscope project has two Java desktop applications: "The Qualitative Dynamical Systems Modeling & Simulation Environment", or QDS MSE, and "The Space Exploration Mission // Agent-Robot Behavior Simulator", or SEM ABS.
Both applications are distributed in the form of their installers assembled for macOS, Windows, and Linux computers. They can be downloaded from this page and placed on the hard disk following the standards of the named OSs. Installers with the extension ".pkg" are intended for installing and executing applications on computers equipped with macOS. Installers having extension ".msi" are intended for installing and running applications on Windows computers. And installers having extension ".exe" are intended for installing and running applications on Linux computers.
All these installers, during the installation of their applications, ask:
1) Accept the End-User Licence Agreement.
2) Choose Application Destination Folder instead of the pre-populated default location that is: a) xxx for MacOS, b) Program Files for Windows, and c) yyy for Linux.
The three groups listed below (each having two buttons) suggest downloading installers for two applications named at the beginning of the page.
Modeling & Simulation Environment - MSE
Agent Behavior Simulator - ABS
