问题描述

I'm using SHGetFolderPath CSIDL_APPDATA to get path to the application data folder under current user account. It works fine, but if it is called from an installer, Windows change it to administrator's folder! How can I get the current user's data folder from an installer?

推荐答案

SHGetFolderPath() has an hToken parameter for this exact situation. If hToken is NULL, the function uses the access token associated with the calling thread. Otherwise it can be set to an access token for another user account.

如果安装程序以管理员身份运行，则安装程序将必须执行以下操作之一:

If the installer is running elevated as an admin, the installer will have to either:

1. 在致电SHGetFolderPath()之前模拟所需的用户帐户.

1. impersonate the desired user account before calling SHGetFolderPath().

获取所需用户帐户的访问令牌并将其传递给hToken.

obtain an access token for the desired user account and pass it to hToken.
