DockingManager and FrameBarManager in Managed C++

I''m having difficulties using several components in manager C++. Specifically the two above, but anything that ''docks'' in the form designer in the bottom section. I get the following message after dropping the control into the bottom container of the form designer: An exception occurred while trying to create an instance of Syncfusion.Windows.Tools.XXXXX. The exception was "The type initializer for "xx.xx.xxxxx" threw an exception. What am I doing wrong?
