callback文件系统:eldos.cbfs.ECBFSError:访问被拒绝

我已经请求回拨文件系统的试用许可证,并尝试使用java编写简单的应用程序! 所以,我写了接下来的几行并运行它,并收到exceptioneldos.cbfs.ECBFSError: Access is denied

  import eldos.cbfs.CallbackFileSystem; import eldos.cbfs.ECBFSError; import eldos.cbfs.boolRef; import java.util.logging.Level; import java.util.logging.Logger; /** * @author Sergii.Zagriichuk */ public class Test1 { private static Logger logger = Logger.getLogger(Test1.class.getName()); public static void main(String[] args) { CallbackFileSystem callbackFileSystem = new CallbackFileSystem(); callbackFileSystem.setRegistrationKey("My registration key "); try { callbackFileSystem.install("<path to cab>\\cbfs.cab", "Test", true, 131072, new boolRef(false)); } catch (ECBFSError ecbfsError) { logger.log(Level.SEVERE, ecbfsError.getMessage(), ecbfsError); } } } 

我该如何解决这个问题? 谢谢
