Thank you for writing.
By default, when you use the MSI installer the demos are installed together with the controls and an icon is placed on the Desktop. Also, they are available in the Telerik folder in your Start Menu.
However, if you have used the web installer, the LocalDemos option is disabled by default (see screenshot for reference), so demos are not installed. Please make sure you have this option enabled when installing. If you continue experiencing difficulties, please let us know.
