问题
I have developed a WIX custom installer using C# WPF. I need to delete a file from "c:\Program Files" using c#. It shows error unauthorised. If i manually run with "run as administrator" it works. I tried adding manifest file and necessary changes. But it didn't work. I tried copying the same manifest file to a console application and it works.

You can do this by creating a C# custom action project and referring it in the WIX project.
