[Inno Setup] 区分Windows版本的一个例子

Windows 8.1 和 Windows Server 2012 R2， 大小版本号是相同的，都是6.3，如何区分

调用 GetWindowsVersionEx，获取 TWindowsVersion 结构体，其中 ProductType 是 VER_NT_SERVER 的是 Windows Server 2012 R2.

The ProductType field can be one of the following values:

  VER_NT_WORKSTATION
  VER_NT_DOMAIN_CONTROLLER
  VER_NT_SERVER

It can also be zero if the product type could not be determined (unlikely). VER_NT_WORKSTATION indicates a non-server edition of Windows (e.g. Workstation, Professional, or Home).
