IACore.dll, IAWinFX.dll, IALoader missing

I have installed the Microsoft Windows SDK for Windows 7 and .NET Framework 4 through this link ( http://www.microsoft.com/downloads/dlx/en-us/listdetailsview.aspx?FamilyID=6b6c21d2-2006-4afa-9702-529fa782d63b ) on a Windows 7 machine and trying to following the instructions about how to create a Handwriting Recognition WPF application using this guide ( http://msdn.microsoft.com/en-us/library/ms754080%28VS.90%29.aspx ).

However, I couldn't find the IACore.dll, IAWinFX.dll and IALoader.dll mentioned inside the g开发者_开发问答uide. I have even done a search in my Windows installation drive just in case they are installed in another location. But it just seems that the files are not even installed anywhere.

Or is there any alternative for me to build a WPF Handwriting Recognition application?

I found it in:

c:\Program Files\Reference Assemblies\Microsoft\Tablet PC\v1.7\
