NetLogo 1.2.1 Downloads

Attention Windows users:

  • NetLogo runs fastest and is most reliable with the IBM 1.1 VM. Therefore we strongly recommend the "Includes Java VM" option. (Questions? See below.)
  • If you are running anti-virus software there may be a long pause (as much as two minutes) near the end of the download process.

Attention Mac OS X users:

  • If you are installing under Mac OS X, you must choose the Mac OS X download. The installer for Mac OS 8 or 9 does not work properly on OS X.

Windows Details:

  • We strongly recommend the "includes Java VM" download option.
  • Choosing this download option installs IBM's 1.1.8 VM for NetLogo's private use only. Other programs on your system are not affected.
  • NetLogo runs much faster on this VM than any other VM, and is more reliable.
  • Even if you have downloaded NetLogo before, you should still choose "Includes Java VM". The bundled VM is not shared between different versions of NetLogo.
  • You should only choose the "without Java VM" download if either:
    • You have already, separately and independently from any NetLogo download, installed the IBM 1.1 VM on your system yourself.
    • You are certain you wish to try using a VM other than our recommended VM.

Other Platform Details:

  • Be sure you have Java 1.1.8 or later installed. Newer Java versions such as 1.3, 1.4, or 1.4.1 should work even better. You can download Java from Sun's site.
  • The download is in the form of a .tar.gz file. You may untar this file into any directory.
  • Once untarred, the NetLogo application is in the NetLogo.jar file in the netlogo-1.2.1 folder.
  • The method for starting the application may be different depending on your operating system and Java virtual machine. You may be able to just double-click the NetLogo.jar file in your file manager. Or, a typical sequence of commands on a Unix-style machine would be: 
    cd netlogo-1.2.1
java -jar NetLogo.jar
  • For the computer HubNet client, substitute HubNet.jar for NetLogo.jar.
