This error may be occurring due to absence of JDK and JRE "bin" path in the System Environment Variables.

Just add path of the JDK AND JRE "bin" folder in Environment Variables and you are good to go.

To add path follow steps :

Step 1 : Right Click,On My Computer/This PC(Windows 8.1).

Step 2 : Click on Properties.

Step 3 : Click on Advanced System Settings in Left Menu and a dialog will open.

Step 4 : Dialog with Advanced Tab, move towards end of dialog and click on "ENVIRONMENT VARIABLES" button.

Step 5 : In System Variables, Add Path of JDK and JRE in variable path / PATH.

Example of JDK and JRE path : 

C:\Program Files (x86)\Java\jre1.8.0_40\bin

C:\Program Files\Java\jre1.8.0_31\bin
