You still need two environment variables setup correctly:
ANT_HOME pointing to the newly delivered ant within the ~dmrc1/ant or your own ant installation with the "ForTask?" Extension and the
PATH Variable the entry to ~dmrc1/ant/bin
more infos about this on the page Installation description for Windows or about installing ant here http://ant.apache.org/manual/install.html If ant is configured properly just enter out of the ~dmrc1/ directory following commands, one after another.
ant config
creates the config files with your given input for a given instance or just creates the default configiuration, which is now "hsqldb-intern"
ant install
