向注册表授予权限

我授予NETWORK SERVICE权限，以访问我需要通过作为NETWORK SERVICE运行的控制台应用程序访问的注册表项。这是我创建密钥和授予权限的方法。

Microsoft.Win32.RegistryKey key;
            key = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE", RegistryKeyPermissionCheck.ReadWriteSubTree);
            RegistrySecurity rs = new RegistrySecurity();
            rs = key.GetAccessControl();
            rs.AddAccessRule(new RegistryAccessRule("NETWORK SERVICE", RegistryRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow));
            key.SetAccessControl(rs);
            key = key.CreateSubKey("RM", RegistryKeyPermissionCheck.ReadWriteSubTree);
            key = key.CreateSubKey("CSVExtraction", RegistryKeyPermissionCheck.ReadWriteSubTree);
            key.SetValue("Failure Tally", "0");

但是，当我尝试使用以下代码将setValue设置为键时，出现错误。下面给出了我用来设置值的代码。

Microsoft.Win32.RegistryKey key;
            key = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE", Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
            key = key.CreateSubKey("RM", Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
            key = key.CreateSubKey("CSVExtraction", Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
key.SetValue("Failure Tally, "1");

但是在这里，我收到一条错误消息，说拒绝访问HKLM / LOCAL MACHINE / SOFTWARE。但是我使用上面的代码添加了访问规则。但是，当我去手动检查访问权限时，该访问权限已添加到WOW6432node。
