On VS2015, you have to add new project (class library). Add a Class to this project and inherits from System.Configuration.Install.Installer . For example:

using System.Collections;
using System.ComponentModel;
using System.Configuration.Install;
using System.Windows.Forms;`

namespace InstallerAction
{
    [RunInstaller(true)]
    public partial class InstallerPathAction : Installer
    {
        //Here override methods that you need for example
        protected override void OnBeforeInstall(IDictionary savedState)
        {
            base.OnBeforeInstall(savedState);
            //Your code and here abort the installation
            throw new InstallException("No master software");
        }
    }
}

Then, in your installer project, add custom action (Select Installer Project > rigth click > View > Custom Actions > Add Custom Action), Look in Application Folder (double click on Application Folder) Add Output (Select class library that has Installer class) Primary output and click OK.

You can use MessageBox into installer class to debug.
