Hi All,

I am trying to add an exception in windows firewall allowed program list.

My app is in .net framework 3.5:
the below link am not able to compile it compiled in framework 4.0
Open Windows Firewall During Installation[^]

I also used the below code

void AddToFirewallException(string ApplicationName, string FilePath)
        {
            // Add exception to windows firewall after installation
            string RegPath =
                @"SYSTEM\ControlSet001\Services\SharedAccess\Parameters\
        FirewallPolicy\StandardProfile\AuthorizedApplications\List";
            string KeyValue = FilePath + ":*:Enabled:" + ApplicationName;

            RegistryKey Key = Registry.LocalMachine.OpenSubKey(RegPath, true);
            Key.SetValue(FilePath, KeyValue);
            Key.Close();
            Key = null;
        }

the above code also works fine when called from a winform, but raise an exception when I called it in the custom action in VS setup project, Actually I want to add my app in the allowed program list during the installation.

Regards,
Nitin
