For information about how to install KSS NG, see the KSS NG Install Guide.
KSS NG is a separate application from the legacy version of Kiwi Syslog Server. If you installed the legacy version of Kiwi Syslog Server, you must either uninstall it or stop the KSS server before installing KSS NG. Legacy Kiwi Syslog Server and Kiwi Syslog Server NG cannot run on the same machine because they use the same listening ports.
