Answer 1

You need to open Software and specify PackG3EGM as the subkey to delete.

Also pass true to the throwOnMissingSubKey param, this will raise an exception if the specified subkey cannot be found

 string keyName = @"SOFTWARE";
            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(keyName, true))
            {
                key.DeleteSubKeyTree("PackG3EGM", true);

            }
