Appian 17.3 Installation Issue

#InstallationandAdministration

Hi All,
I'm working on 17.3 installation, but I'm getting an error starting Elastic search, it seems like the new hotfix (Hotfix Package B) is missing a plug in or a component. Do you have any advice on the installation?

Regarding the logs it says:
--
[com.appian.es.bootstrap.NodeInit] Failed to initialize ElasticSearch node on port 9300. If other ports for this host are specified in appian-topology.xml, those will be tried as well.
java.lang.IllegalStateException: Could not load plugin descriptor for existing plugin [appian-elasticsearch-auth]. Was the plugin built before 2.0?
--

Thank you in advance!
