Is java in your PATH environment variable? (If you go to the command prompt and type “java”, does it recognize the command? ) By default, Ignition expects java to be defined in your path. You can also explicitly state the path to the java command in the wrapper.conf file. I once had a system that wouldn’t start after an install (just like for you, installed successfully, but failed at the end when starting the service), and after checking all kinds of system settings to no avail, it ended up being as simple as that.
Good luck!
