WIX installer to existing project

I have a WIX installer project in VS2017 that is working. The Installer contains 2 parts of the software. I want an WIX installer option that let the user choose 1 or both of the software component(s). One components needs to be installed as Administrator. Bonus: Automatic Registration of One component (STL thumbnail Provider) with FileExplorer restart = Run a program at end of installation if user choose that. (checbox). Lazy variant is that the GUI for registration is launched. This option should only be available if the STL thumbnail Provider component is choosen. There is already a checkbox at the last Installation screen to launch the main component. I want a review of the WIX installer to see if there is parts that can be improved. The code is available on GIT , but I want you to work on my develop branch. After the project the work will be added to git as a new release.
