Thank you for the reply
It's showing an error message which says " The driver being installed is not validated for this computer.Please obtain the appropriate driver from the manufacturer". I tried the steps as you said and i don't know why, but I could not find the igdlh64.inf or igdlh.inf file in the Graphics sub-folder or any other folder. I am using windows 8.1* 64 bit.
