Simply close the old program.

Keep the separate updater program, then when you want to update your old program, get the updater to close the old program, then download the new version of your app. For example,

Updater program,

 Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
    Do While True
        Dim client As New Net.WebClient
        Dim newVersion As String = client.DownloadString("http://www.myWebsite.com/updates/latestVersion.txt")
        If newVersion <> IO.File.ReadAllText("Your programs file location") Then
            For Each p As Process In Process.GetProcesses
                If p.ProcessName = "your program's process name" Then 'If you don't know what your program's process name is, simply run your program, run windows task manager, select 'processes' tab, scroll down untill you find your programs name.
                    p.Kill()
                End If
            Next
            IO.File.Delete("old program file location")
            client.DownloadFile("http://www.myWebsite.com/updates/12.05.2013.exe", "where ever you want to download your new program to (file location)")
            client.Dispose()
        End If
        Threading.Thread.Sleep(300000) 'freeze thread for 5 mins...
    Loop
End Sub
