I have created a class library that I added into the setup project. That class library is based on the System.Configuration.Install.Installer class. In it, I have the proper code to interact with the setup. Then, I added that class into "Custom Actions\Install" section. However, when I run setup.exe, at the end, it doesn't run that code.

The code is as follow:

Public Class Main

    Inherits System.Configuration.Install.Installer

    Public Sub New()
    End Sub

    ' Override the 'Install' method.
    ' The Installation will call this method to run the Custom Action
    Public Overrides Sub Install(ByVal savedState As IDictionary)
        MyBase.Install(savedState)

        System.Windows.Forms.MessageBox.Show("1")

        ' Get readme file name from custom action parameter
        Dim ProvidedName As String = Me.Context.Parameters("file")

        System.Windows.Forms.MessageBox.Show(ProvidedName)

    End Sub

End Class

So, basically, I should see a message box with "1" as well as a value that I defined in the Custom Action Properties of the class:

CustomActionData=/file="test"

Basically, the goal here is to collect a textbox value, from a custom dialog, and save that into a Main.ini file into the System\Key value. I haven't found a way to do it from the interface. So, I assume I have to define a class library, add it into the project, base it on the Installer class, and found a way to read the custom dialog Key textbox value and store it in the Main.ini file.

Anyone has done that before?
