Hey, you are trying to install way too old versions for watcher and the license plugin. Those are intended to run with Elasticsearch 1.x Please follow the [offline installation guidelines](https://www.elastic.co/guide/en/watcher/2.4/installing-watcher.html#offline-installation) for Elasticsearch 2.x, which contains the right URLs. --Alex ---
