Requirements
Java version 1.8 or above (JDK 1.8) is a pre-requisite for running this software.
You can download the JDK 1.8 or higher version from http://www.oracle.com/technetwork/java/javase/downloads/jdk8_downloads_2133151.html
Also ensure that the path to this java version is added (at the beginning) to the system PATH variable.
Example:
Assuming you have installed Java in C:\Program Files\Java\jdk1.8.0_05, then edit the PATH system variable and add C:\Program Files\Java\jdk1.8.0_05\bin to the beginning of your PATH variable. This ensures that the jdk 1.8 is picked up everytime.
If your PATH variable has C:\WINDOWS\SYSTEM32 (before jdk 1.8 is added to PATH) then after adding the JDK1.8 the path changes to - C:\Program Files\Java\jdk1.8.0_05\bin;C:\WINDOWS\SYSTEM32.
To set the PATH system variable for different version of WINDOWS OS, see http://www.java.com/en/download/help/path.xml
