Logisim should run on any platform supporting Java, version 1.4 or later.

  1. Logisim requires Java 1.4 or later. If you do not already have it on your computer, Java is available from
  2. Download Logisim from links given below. You will three choices of which release to download.
    • A .jar file - runs on any platform, though not necessarily conveniently.
    • A MacOS .tar.gz file
    • A Windows .exe file
    If you use MacOS or Windows, I would recommend using the release specific to your platform.
  3. To execute the program:
    • With the generic .jar file: On Windows and MacOS systems, you will likely be able to start Logisim by double-clicking the JAR file. If that doesn't work, or if you use Linux or Solaris, you can type ``java -jar logisim-XX.jar'' at the command line.
    • With the MacOS X version: Once the downloaded .tar.gz version is uncompressed (this will likely happen automatically), just double-click the Logisim icon to start. You may want to place the icon into the Applications folder.
    • With the Windows version: Just double-click the Logisim icon. You may want to create a shortcut on the desktop and/or in the Start menu to make starting Logisim easier.
