You did not show the output of the first call. Anyway I believe you did not restart your nodes. ---

It depends on how you started it and what is your OS. ---

okay. I have set up on the windows 7 machine. Just installed the elastic search file and then configured as given in the official doc. then started service by entering `elasticsearch`. but DNW command for stopping the elastic search service. ---

I don't know windows but I suppose that if you go to "services" in the admin menu, you will see elasticsearch and you can stop it and start again... ---

Once you have restarted, what is the output of: ```auto GET /_cat/plugins?v ``` If empty, then you probably did not install the plugin well. ---

Probably you need to change that: [https://www.elastic.co/guide/en/elasticsearch/plugins/6.5/\_other\_command\_line\_parameters.html#\_custom\_config\_directory](https://www.elastic.co/guide/en/elasticsearch/plugins/6.5/_other_command_line_parameters.html#_custom_config_directory) But may be someone from the Microsoft team could help. ---

I have solved the issue by just killing the elastic search by using PID then I restarted the elastic search once again and installed the analyzer plugin. ---
