            ErrorString(dwRes);           //OK
      dwRes= RegOpenKeyEx(hKey,"Software",0,KEY_READ|ACCESS_SYSTEM_SECURITY,&hObject);
    //  SetPrivilege (SE_SECURITY_NAME, true); needed ?
             ErrorString(dwRes);                // OK
      PSECURITY_DESCRIPTOR psd = NULL;
     PSID   owner_sid;
      PSID   group_sid;
