Instalando COCO/R no eclipse

Assuntos Gerais
#1

Estou tentando instalar o COCO/R para desenvolver um Parser e um Scanner no Eclipse (seguindo por teste tutorial: http://ssw.jku.at/Coco/Java/Static/EclipsePlugin/coco.html), ou seja, desenvolver um compilador.
Porém ao tentar configurar o launcher do COCO/R tenho o erro abaixo:
