An appropriate Windows Platform SDK is included by default in the full (not express/lite) versions of Visual version of the Platform SDK. To use Visual C++ 6.0 or 7.0 (Studio 2000 .NET), the Platform SDK environment must be prepared using the setenv.bat script (installed by the Platform SDK) before starting the the command line build or launching the msdev/devenv GUI environment. Installing the Platform SDK for Visual Studio Express versions (2003 and later) should adjust the default environment appropriately.
