尝试运行卷影复制时"procedure entry not found in vssapi.dll"出现运行时错误

Question

代码编译良好，我已将vssapi.lib包含在链接器的附加依赖项中。

我收到这个错误，说"在vssapi.dll中找不到CreatevssbackupcomponentsInternal过程入口点"

只有当我尝试在Windows服务器2003或Windows XP上运行它时，才会出现这个错误。它在Windows7上运行良好。

我将在下面附上代码，这是标准的影子复制代码。

您必须使用Windows Vista之前的Windows版本的Windows卷影复制SDK：http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=23490
