This is a UAC thing. You have your program run as administrator for creating/deleting files/folders in this SpecialFolder.
这是 UAC 的事情。您以管理员身份运行您的程序，以在此特殊文件夹中创建/删除文件/文件夹。

An easy to understand explanation of the different places you can store program data can be found here:
可以在此处找到有关可以存储程序数据的不同位置的易于理解的说明：
As regards ProgramData, it says:
至于 ProgramData，它说：
FOLDERID_ProgramData / System.Environment.SpecialFolder.CommonApplicationData The user would never want to browse here in Explorer, and settings changed here should affect every user on the machine. The default location is %systemdrive%\ProgramData, which is a hidden folder, on an installation of Windows Vista. You'll want to create your directory and set the ACLs you need at install time.
FOLDERID_ProgramData / System.Environment.SpecialFolder.CommonApplicationData 用户永远不想在资源管理器中浏览此处，此处更改的设置应该会影响机器上的每个用户。默认位置是 %systemdrive%\ProgramData，这是 Windows Vista 安装中的一个隐藏文件夹。您需要在安装时创建目录并设置所需的 ACL。

it is a conceptual issue at first look:
乍一看，这是一个概念问题：
You should NOT use the "ProgramData" directory but some user specific files. Needed installation data should installed in the "program files" or in the registry.
您不应使用“ProgramData”目录，而应使用某些特定于用户的文件。需要的安装数据应该安装在“程序文件”或注册表中。
