Sometimes this problem is created by the antivirus program installed in your system. Set the antivirus to "Disable until the computer is restarted" option. In my case, I had installed Avast antivirus. I disabled it by: right click avast in notification area >> Avast shields control >> Disable until computer is restarted.
