Java Install4j安装中的NotSerializableException作为普通用户

我正在编写一些Java代码，作为使用Install4j创建的安装程序的一部分。 我的部分脚本如下所示-

     String result = (String)context.runElevated(new RemoteCallable() {
            public Serializable execute() {
            try {
                File dir = new File ((String)context.getVariable("sys.installationDir"));
                File [] files = dir.listFiles();
                for (File file : files)
                {
                    if (file.isFile())
                    {
                        file.delete();
                    }
                    else if (file.isDirectory())
                    {
                        File subDir = new File(file.getAbsolutePath());
                        File [] subFiles = subDir.listFiles();
                        for (File subFile : subFiles)
                        {
                            subFile.delete();
                        }
                        subDir.delete();
                    }                        
                }
                }
                catch(Exception e)
                {
                    Util.showWarningMessage("asdasdasdasd");
                }
                return "The computed value";
            }
        }, true);

现在，如果我以管理员身份运行创建的安装程序，我不会收到任何错误，但作为普通用户，我会收到

java.io.NotSerializableException

作为一个C++程序员，我不知道这意味着什么，或者为什么会发生这种情况。 如果有人能帮我解释一下，我将不胜感激

谢谢

这是日志文件

您不能将上下文带到远程助手进程。将此行放在

可运行

外的顶部：

final File dir = new File ((String)context.getVariable("sys.installationDir"));

---

然后它应该可以工作。

您可以发布异常的堆栈跟踪吗？将此添加到代码中：e.printstacktrace（）什么类型的对象是上下文？添加的日志文件-上下文位于作为Install4j api一部分声明的对象上
