Click once is a great way to install win form applications within your organization. One issue I discovered recently is that the installed application’s icon does not appear in the Add/Remove programs (or Program and Features) dialog screen. This does not look very professional.

Searching the internet I found a work around here (this has both C# and VB.Net examples):

I made a few changes to the VB.Net code which I share below. A few issues I found that you should keep in mind:

• Icon file should be set to Copy Always for the property Copy to Output Directory
• Make sure your display name and product name match exactly as these are compared.
• Icon is only updated on the first run of the application after install, so if you’re testing this code you will need to un-install before the next test/install.

Here’s my code, you will need to replace the calendar.ico text with your icon file and add the imports.

   Imports System.Deployment.Application
   Imports Microsoft.Win32

   Sub SetAddRemoveProgramsIcon()
        Try
            'only run if deployed 
            If ApplicationDeployment.IsNetworkDeployed And ApplicationDeployment.CurrentDeployment.IsFirstRun Then

                Dim iconSourcePath As String = System.IO.Path.Combine(Application.StartupPath, "calendar.ico")

                If Not File.Exists(iconSourcePath) Then
                    Return
                End If

                Dim myUninstallKey As RegistryKey = Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Uninstall")
                Dim mySubKeyNames As String() = myUninstallKey.GetSubKeyNames()

                Dim i As Integer
                For i = 0 To mySubKeyNames.Length

                    Dim myKey As RegistryKey = myUninstallKey.OpenSubKey(mySubKeyNames(i), True)
                    Dim registryAppName As Object = myKey.GetValue("DisplayName")
                    Dim registryAppVersion As Object = myKey.GetValue("DisplayVersion")
                    If registryAppName <> Nothing And registryAppVersion <> Nothing And
                        registryAppName.ToString().StartsWith(Application.ProductName) And
                        registryAppVersion = ApplicationDeployment.CurrentDeployment.CurrentVersion.ToString() Then

                        myKey.SetValue("DisplayIcon", iconSourcePath)
                        Exit For

                    End If
                Next

            End If

        Catch ex As Exception
            Throw
        End Try
    End Sub

Let me know if you have any questions.
