Hi Smriti\Telerik support,
I think I am facing the same problem:
I built a VSTO project with an ElementHost that hosts 2 WPF telerik controls. Works good on my developer machine.
Published as Clickonce and when deploying and executing on client machine the 2 WPF controls are not visible.
I am using (I think) the controls that I just bought and downloaded so it should be the Licensed version Q2 2016.
In my solution - all the Telerik references are set as "Copy Local" and are present under the "publish" directory.
How can I make sure I am using the Licensed versions and are there any other reasons that can cause this problem?
