How to fix the Error Microsoft Setup Bootstrapper has stopped working

Microsoft has constantly attempted to upgrade installation of their products by implementing most recent technologies. In Previous years, we have utilized executable documents which were equipped capable of installing a product with a single click.  But, in office 2013/2016, Microsoft is using Bootstrapper technology.

Bootstrapper: A Bootstrapper is responsible for the introduction of an application built using the composite application library. Having a Bootstrapper gives you more control of how the composite Application library components are wired up to your application. You can explore more about Bootstrapper technology on MSDN. For example: if you have an existing application that you are adding the composite Application library to, you can instate the bootstrapping process after the application is already running.

In WPF (Windows Presentation Foundation) application, a startup Uniform Resource Identifier is specified in the app.xaml that launches the main window. In an application created with the Composite Application library, it is the Bootstrapper’s responsibility. This is because the shell depends on services that should be registered before the shell can be shown. Moreover, the shell may depend on other services that are infused into its constructor.

The Composite Application Library includes a default conceptual UnityBootstrapper class that handles this initialization utilizing the Unity container. Many of the strategies on the UnityBootstrapper class are virtual techniques. You should override these techniques as suitable in your own custom bootstrapper execution. If you are using a container other than Unity, you ought to compose your own container-specific bootstrapper.
