Implement elasticsearch in Laravel 4 on a windows environment

I have a project which works fine on the server with linux ubuntu environment. The problem started when I pulled the project (from github) to my local system which has windows 7 installed.

I got the project pulled it to my local system and used composer, since the project was built using laravel 4, to install the dependencies. I noticed that a folder named elasticsearch\elasticsearch was created in the vendor folder as shown below.

After that I tried to check whether elasticsearch is working it get an error message as below:

This works fine on the server (with ubuntu).

Where could I go wrong? What did I miss?
