Problem:

When calling a native program from within a Run Unit you get the following error:

173 error on RunUnit.Call("Program")

Resolution:

The way to configure your Visual Studio solution to pick up the legacy programs is to:
 
1. Add the legacy program to a class library project.
 
2. Add a reference within your program and created an instance of the class.
