I downloaded Watij Release 3.2.1 from Sourceforge, dragged the zipfile to a folder on my desktop, unzipped the file, and then doubleclicked on launchWatijBeanShell.bat.
This resulted in the following error: Couldn't start desktop: Sourced file: inline evaluation of: "desktop();" : Object constructor : at Line: 28 : in file
/bsh/commands/makeWorkspace.bsh : makeWorkspace ( "" + windowCount ++ )
