Question

I have a .NET application deployed via ClickOnce. The application icon shows fine on the start menu, task bar, etc., but not in the Add / Remove Programs in the control panel. What do I need to do to fix this?

Answer 1

This isn’t supported by ClickOnce (although I keep asking for it).

I collected the following code ages ago, but I have never had time to try it out. I’d put a try/catch around it in case it causes a problem. Let me know if it works. 😉

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 , true);
    object myValue = myKey.GetValue("DisplayName");
    if (myValue != null && (string)myValue == _ApplicationName)
    {
        myKey.SetValue("DisplayIcon", _ExecutablePath + @"\App.ico");
        break;
    }
}
