Most of Ignition 7.9.x _ **requires** _ Java8 installed on the client. Later versions (starting with 7.9.10, IIRC) include a java9 runtime in the launcher that can be used no matter what other version is installed in the client. Short term: reinstall java 8. Long term: upgrade to a newer version of 7.9.x. ---
