You have two versions: with Installer or extractable packages (7-Zip) The Installer version offer to register as default executing option for .rb files and also allow you add Ruby to the search path. This option is not portable. The 7-Zip package is portable, extract on any directory, add the bin directory to the PATH (as explained before) and call scripts with "ruby myscript.rb" Is not Cygwin nor install it. -- Luis Lavena
