推荐答案

您应该致电 SHGetKnownFolderPath 提供 FOLDERID_ProgramFiles 文件夹 ID.它将为应用程序检索正确的目录.如果你仍然想安装到system32中(虽然典型的应用程序不应该这样做)，那么你可以用FOLDERID_SystemX86调用它.

You should call SHGetKnownFolderPath supplying FOLDERID_ProgramFiles folder id. It will retrieve correct directory for applications. If you still want to install into system32 (though typical applications should not do it), then you can call it with FOLDERID_SystemX86.
