java.lang.UnsatifiedLinkError无法加载dll

您好，我是JRegistryKey的gettin lang UnsatifiedLinkError。我正在Windows 7 32位上使用Netbeans 8.0.2。jRegistryKey.dll位于我的项目根文件夹和路径变量中。 我在这里得到一个例外：

 RegistryKey.initialize("jRegistryKey.dll");
  RegistryKey key = new RegistryKey(RootKey.HKLM,"Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\CheckpointDRG");
  Iterator<RegistryKey> subkey = key.subkeys();

Exception in thread "main" java.lang.UnsatisfiedLinkError: ca.beq.util.win32.registry.RegistryKey.testInitialized()V
