We set our assembly description to the same string as our Product Name, so we can look through the uninstall strings for the right application by searching for the assembly description. This way, we don't have to hardcode the product name in this code.</p> <pre><code> private static void SetAddRemoveProgramsIcon() { //only run if deployed if (System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed &amp;&amp; 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, "youriconfile.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 &lt; mySubKeyNames.Length; i++) { RegistryKey myKey = myUninstallKey.OpenSubKey(mySubKeyNames[i], true); object myValue = myKey.GetValue("DisplayName"); if (myValue != null &amp;&amp; myValue.ToString() == assemblyDescription) { myKey.SetValue("DisplayIcon", iconSourcePath); break; } } } catch (Exception ex) { //log an error } } } </code></pre>
