MicroWorlds EX, the current iteration of the software, was released in 2003 for Windows 98 and up (currently supported for Windows 7 and up), and in 2004 for Mac OS X. A “Robotics edition” was released for both platforms that worked with Lego RCX programmable bricks and the Handy Cricket microcontroller system. An "Exploring Math" module intended for Grades 4-7 was released in 2005 and a "Computer Science" module released in 2013. The program has been made available in French, Spanish, Russian, Chinese, Portuguese, Italian, Armenian, and Greek. MicroWorlds EX will not work with macOS 10.15 or higher due to requiring 32-bit support.
