Issue in running sikuli script in windows machine

I am trying to automate the opening of notepad using Sikuli in windows OS.

Source Code :

import org.sikuli.script.FindFailed;
import org.sikuli.script.Pattern;
import org.sikuli.script.Screen;
import org.testng.annotations.Test;

public class Notepad {

    Screen s=new Screen();

    @Test

    public void opennotepad() throws FindFailed{

        Pattern notepadIcon = new Pattern("src/icon.png");
        s.click(notepadIcon);

    }
}

I am getting the following error:

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5. [error] ResourceLoaderBasic: checkLibsDir: libs dir is not on system path: C:\Users\Salini.LS\Desktop\Automation\Automation\JAR Files\libs [action] ResourceLoaderBasic: checkLibsDir: Please wait!
