I'm confused by the commands given by Tomcat documentation about creating different instances, it says: "service install instance1" but "service" is not a command provided by Tomcat or Windows, see http://tomcat.apache.org/tomcat-7.0-doc/windows-service-howto.html#Multiple_Instances
Almost everything I'm trying to automate using that page is not working, maybe it's rare people automate installation on Windows?
