In the control panel window, double-click Add/Remove Programs
In the program list, if there is an entry saying "Java Media Framework ...", you should have it installed. Otherwise, your machine does not have Java Media Framework installed or not installed properly.
If you want to install/re-install Java Media Framework, please follow the instructions in the Java Media Framework Installation Guide.

Hi amit_n_panchal

I have tried the link and I am getting the message

"Old and unsupported versions of Java have also been detected on your system.
Click here for instructions on how to remove them to maintain your system security"

Then I download the installer after the installation as well I am getting the same error. Is there anything that I have missed,

Hi amit_n_panchal

I am new to Java so I am not aware of the versions. My requirement is I want to practise core Java.
Commented:
Do one thing.

Uninstall all the java versions from your machine. Download the latest version from the below link and install it.

http://www.oracle.com/technetwork/java/javase/downloads/index.html

With the latest version of Java, you can also practice new features of the latest release.

Hi Karan, I hope my last post makes you smile! (my weak sense of humor at its best). You are like me, new to java. If i may speak off topic, id like to recommend these two books. I am about half way through the first book. I think they are very well done.

hi kiran.
u have 3 versions of java, so remove two of them.
or remove all 3 versions & download one latest version of java.
