title: Where is DXGI1_2.h under Windows 7?
body: <p>I am using Visual Studio 2008 to compile some code under Windows7. But there is an error:</p>
  
  <pre><code>Error   44  fatal error C1083: Cannot open include file: 'DXGI1_2.h': No such file or     directory c:\users\administrator\desktop\tightvnc-2.7.7\desktop\wind3d11device.h  33
  </code></pre>
  
  <p>I have installed DirectX, and I don't know which SDK I should install to let VS2008 find DXGI1_2.h.</p>
  
  <p>What should I do to get this DXGI1_2.h?</p>
