mkdirs在Windows 7中不起作用

我制作了一个小型的Java应用程序，可将目录从CD复制到HD.我使用Windows Vista制作了该程序，并且可以运行，但是当我在Windows 7中运行它时，它失败了.

I made a small java app that copies a directory from a CD to the HD. I made the program using Windows Vista and it worked, but when i ran it in Windows 7, it fails.

主要问题是需要在Program Files文件夹中创建一个文件夹.

The main problem is that a folder inside the Program Files folder needs to be created.

我使用了DestinationFolder.mkdirs()，但是创建它失败

I used DestinationFolder.mkdirs(), but it fails creating it

这是Java代码:

public void Install_App()
{
    File srcFolder = new File(System.getProperty("user.dir") + "\\WINDOWS");
    File destFolder = new File("C:\\Program Files\\test1\\test2\\");
    if (srcFolder.exists())
    {
        try{
            if(!destFolder.exists())
        {
            destFolder.mkdirs();
        }
            copyFolder(srcFolder,destFolder,1);
        }catch(IOException e){
            e.printStackTrace();
            JOptionPane.showMessageDialog(null, e.toString());
            error=true;
            System.exit(0);
            }
    } else 
    {
        JOptionPane.showMessageDialog(null, "Error. Source Directory doesn't exist.");
        error=true;
    };
} 

...，然后有一个copyfolder函数，该函数可使用inputstream和outputstream复制文件.

... and then there is a copyfolder function that copies the files with inputstream and outputstream.

问题是文件夹从未创建.我的登录用户是管理员.正如我所说的，它可以在Vista中使用.

The problem is that the folder is never created. My login user is an administrator. And as i said, it worked in Vista.

可以帮我吗?

谢谢.

问题是我在Java中创建了这个应用程序，以便在Windows和Mac上运行它. 在Windows中，应使用和autorun.inf自动运行，如下所示:

The thing is that i created this app in java to run it in Windows and Mac. In Windows it should autorun with and autorun.inf like this:

[autorun]
OPEN=java_app.bat

然后这只蝙蝠将运行:

@echo off
start javaw -jar "java_app.jar"
EXIT

那么我该如何修改它以使其以管理员身份自动运行? 此Java应用程序的主要思想是简化安装和安装过程.无论您使用哪个操作系统，都可以使用外部应用程序.如果我必须要求用户以admin身份运行它，那么它将失去(使用简单)的感觉.

so how can i modify it to run it as administrator automatically? The main idea of this java app is simplify the process of install & use an external application no matter which OS are you using. If I have to ask the user to run it as admin it will loose it's sense (of been simple of use).
