CUDA Visual Studio extension Instructions don't apply

In the file MSBuildExtensions.README.txt located in C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\extras\visual_studio_integration, it says “These files should not be used directly from this folder. To deploy files, copy all files under MsBuildExtension subfolder directly into C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\BuildCustomizations (C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\BuildCustomizations on 64 bit) folder.”

I’m running Windows 7 64bit and there is no such folder.
