Hi Srinivasan,
The Live demos have been shipped with a separate installation since several releases and are not installed with the default installation of the controls. You can either install them separately through the
Telerik_UI_for_ASP.NET_AJAX_2017_3_913_Demos_Trial.msi file or download the zip archieve of the controls, where the Live Demos folder is included (
Telerik_UI_for_ASP.NET_AJAX_2017_3_913_Trial.zip)
