How do you tell InstallShield LE which project in the solution to install? I have added the installer project to my solution and I don't see where to tell it which project needs to be included into the install. Currently it just installs a blank folder.
Authoring installers is development. InstallShield LE doesn't automagically look at your solution and decide for itself how to deploy your projects.
Take a look at InstallShield Limited Edition for Visual Studio 2010 Walkthrough for a high level walkthrough.
