You must have Java installed on your computer before you can run Populus.

To get Java please download Java from this website.

Populus has been tested on Windows XP (not recommended), Windows 7, Windows 8, Windows 8.1, and Windows 10. Please ensure .jar files are associated with the Java Runtime Environment (JRE). For more information on how to do this, please see this page. You may also need to re-install Java if the .jar file association does not work.

Mac OS X 10.8, 10.9, or 10.10 users may get the error "App can’t be opened because it is from an unidentified developer” in order to bypass this error you will need to right-click (or control-click) PopulusAll.jar and click Open and then Open again at the popup box .
