Fatal error c1083 не удается открыть файл включение windows h no such file or directory

First of all: I’m using Microsoft Visual Studio 2012

I am a C#/Java developer and I am now trying to program for the kinect using Microsoft SDK and C++. So I started of with the Color Basics example, and I can not get it to compile.
At first, none of the classes were able to find Windows.h. So I installed (Or re-installed, I’m not sure) the Windows SDK, and added the include dir of the SDK to the include «path» of the project. Then all the problems were gone, except for one:

Error   5   error RC1015: cannot open include file 'windows.h'. C:\temp\ColorBasics-D2D\ColorBasics.rc  17  1   ColorBasics-D2D

And thats the error. No reasons why, the system can find it because it is used in multiple other files, only this file is not able to work with it. As a reference, the entire file that is bugging (ColorBasics.rc):

I’m trying to get IKVM to build (see this question) but now have encountered a problem not having to do with IKVM so I’m opening up a new question:

When running nant on the IKVM directory with the Visual Studio 2008 Command Prompt (from the Start Menu), I get the following error:

        ikvm-native-win32:

               [cl] Compiling 2 files to C:\ikvm-0.36.0.11\native\Release'.

               [cl] jni.c
               [cl] os.c
               [cl] C:\ikvm-0.36.0.11\native\os.c(25) : fatal error C1083: Cannot open include file: 'windows.h': No such
                    file or directory
               [cl] Generating Code...

        BUILD FAILED

        C:\ikvm-0.36.0.11\native\native.build(17,10):
        External Program Failed: cl (return code was 2)

I have the Platform SDK installed. What am I missing? I’m sure it’s something simple…

Edit #1 I just checked — I do have the directory containing windows.h on the Path.
Edit #2 Found the answer (see my answer below): The directory containing windows.h needed to be in the «Include» path variable.
