How to register an addin through exe/installer ?

I am following  Taskpane tutoral (C# SolidWorks API Tutorial - 01 Getting Started Creating Taskpane - YouTube ). I created an exe for the addin. But, when I go through the installation process it does not register the addin. 

Question: I don't want to have a user manually register the addin. What can I do so that when the user runs the exe/installer the registry will update and addin will show up in Solidworks.
