Unable to load JNA native support library Elasticsearch 6.x

Question

I have installed Elasticsearch 6.x in my Debian 7 (wheezy). I tried to start with service elasticsearch start but its give me an error message

Answer 1

The same problem happened to me on Windows 10 when running from command prompt:

unable to load JNA native support library, native methods will be disabled.

To solve this, it was enough to run elasticsearch.exe with Admin rights (Click Start -> type "Command" -> right click on "Command Prompt" -> select "Run as Administrator")
