I have the same exact problem. Has anyone ever figured this out?
From: Matthew Lenda on 23 Apr 2010 20:21 The issue was that I needed the Windows Visual Studio 2008. It has the proper *things* to run embedded code in Simulink. Go get it! I only found out about this because a buddy of mine ran into the same problem when working on similar things. I would have had no idea otherwise!

I would have had no idea otherwise! Hi Matthew, I was wondering what you did to solve this. I'm having the same problem at the moment, but I've installed the MS SDK (x64 compilers) and MS Visual Studio 2008, but I still can't get things to work. See my posts on the related thread: http://www.mathworks.com/matlabcentral/newsreader/view_thread/270052 Chris
