How to use licenses.licx in a C++/CLI application

So we just purchased a bunch of copies of the Tools product for Windows Forms and are having licensing issues using it inside a C++/CLI application within VS 2008 (the evaluation version worked fine of course).

So we've added licenses.licx to our project, but when I pull up the properties for that file I don't have an option to choose "Embedded Resource". Instead I have "Managed Resource" and "Resource Compiler Tool". If I choose "Managed Resource" it fails. If I choose "Resource Compiler Tool" I get

error RC2135 : file not found: SYNCFUSION.CORE

All of the hits I can find on how to do this are for C# or VB. What about C++/CLI???

I believe we have added the correct project references to the project although it is hard to know!
