First of all, you have my admiration and thanks for demonstrating how to create a Windows Service for the purpose of sending automated emails. I currently have that very requirement.
Unfortunately, in VS 2012 Microsoft removed the Visual Studio Installer and left its customers with InstallShield. What is your recommendation for for a Windows Service installation tool? Do you know where I and others can find step by step instructions for the implementation of your recommended tool in the installation of a Windows Service?
