Hello Abhishek,
for installing KDS - Kinetis Design Studio Integrated Environment (IDE)
and according to your platform please download the executable file.

For additional information you can see documentation for KDS, be aware you install 2.0

The procedure is very easy, firstly you must accept the conditions,


and that´s it. The workspace would probably be at C:\Users\<your profile>\workspace.kds and KDS folder could be here C:\Freescale\KDS_2.0.0
for installation KSDK, please visit Freescale MQX™ RTOS for Kinetis SDK|Freescale and Download it according to your platform

You can go back after installation and modified it, don´t worry.
