(includes MDAC 2.8, Tablet 1.7 and Windows Installer 3.0)

side with the Windows Server 2003 SDK or standalone but will not provide

build environments for:

Windows Advanced Server, Limited Edition

Windows XP

Windows XP 64-bit Edition

Windows 2000

Windows Server 2003 for those environments.The SDKs can not be installed in

the same directory for side by side performance.

Windows Server 2003 SP1 Platform SDK Web Install，最新版的SDK，可惜不能和VC6一起协作，不再支持NT4和9X。

Supported Operating Systems: Windows 2000; Windows Server 2003; Windows XP 64-bit; Windows XP Professional Edition ; Windows XP Service Pack 1
This SDK does not support working with Microsoft Visual C/C 6.0 as support for VC 6.0 has ended. The last SDK that will work with VC 6.0 is the February 2003 Edition.

若你使用的是Visual C++ 2005 Express Edition，请参考：Using Visual C++ 2005 Express Edition with the Microsoft Platform SDK。
