Is there a way to change the icon of a ClickOnce application in 'Add or Remove Programs'?

Question

I have one Windows application which is deployed using ClickOnce technology. Is there a way to change the icon of that application which is shown in the image?

Answer 1

Setup: Visual Studio Enterprise 2015, WPF, C#

1. Go to Solution Explorer
2. Right-click on your ProjectName then click 'Properties'.
3. Click Application as shown below. Remember your icon name.

4. Click 'Publish' on the left column.
5. Click 'Options...' button on the right.
6. 'Publish Options' window should pop up as shown below. Remember what's in the 'Product name:' field. In the example below, it's "MyProductName"

6. Copy and paste the following code in your main class.

    private void SetAddRemoveProgramsIcon()
    {
        if (ApplicationDeployment.IsNetworkDeployed && ApplicationDeployment.CurrentDeployment.IsFirstRun)
        {
            try
            {
                var iconSourcePath = Path.Combine(System.Windows.Forms.Application.StartupPath, "MyIcon.ico");

                if (!File.Exists(iconSourcePath)) return;

                var myUninstallKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall");
                if (myUninstallKey == null) return;

                var mySubKeyNames = myUninstallKey.GetSubKeyNames();
                foreach (var subkeyName in mySubKeyNames)
                {
                    var myKey = myUninstallKey.OpenSubKey(subkeyName, true);
                    var myValue = myKey.GetValue("DisplayName");
                    if (myValue != null && myValue.ToString() == "MyProductName") // same as in 'Product name:' field
                    {
                            myKey.SetValue("DisplayIcon", iconSourcePath);
                        break;
                    }
                }
            }
            catch (Exception uhoh)
            {
                //log exception
            }
        }
    }

7. Call SetAddRemoveProgramsIcon in the constructor.

    public MainViewModel()
    {
        SetAddRemoveProgramsIcon();
    }

Answer 2

The following code is what I used for solving the problem. I used Stack Overflow question Custom icon for ClickOnce application in 'Add or Remove Programs'.

    private static void SetAddRemoveProgramsIcon()
    {
        //only run if deployed
        if (System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed
             && ApplicationDeployment.CurrentDeployment.IsFirstRun)
        {
            try
            {
                Assembly code = Assembly.GetExecutingAssembly();
                AssemblyDescriptionAttribute asdescription =
                    (AssemblyDescriptionAttribute)Attribute.GetCustomAttribute(code, typeof(AssemblyDescriptionAttribute));
               // string assemblyDescription = asdescription.Description;

                //the icon is included in this program
                string iconSourcePath = Path.Combine(System.Windows.Forms.Application.StartupPath, "hl772-2.ico");

                if (!File.Exists(iconSourcePath))
                    return;

                RegistryKey myUninstallKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall");
                string[] mySubKeyNames = myUninstallKey.GetSubKeyNames();
                for (int i = 0; i < mySubKeyNames.Length; i++)
                {
                    RegistryKey myKey = myUninstallKey.OpenSubKey(mySubKeyNames[i], true);
                    object myValue = myKey.GetValue("DisplayName");
                    if (myValue != null && myValue.ToString() == "admin")
                    {
                        myKey.SetValue("DisplayIcon", iconSourcePath);
                        break;
                    }
                }
            }
            catch (Exception ex)
            {
                System.Windows.Forms.MessageBox.Show(ex.Message.ToString());
            }
        }
    }
