I'm trying to build the Mig Alley source code, and it needs an old version of DirectX. The issue is that DirectX is now included with the Windows SDK, so it keeps conflicting with the old DirectX SDK I'm trying to use. I've tried excluding the path, and rearranging my include paths to have the Windows SDK first.

Does anyone have any ideas? I can't get the correct DirectX 6 SDK to be used.

Errors:
