How can I resolve the error message 'The type initializer for 'Nested' threw an exception' when trying to start the Delsys Trigno Control Utility?

This error can be resolved by going to C:\Users\[username]\AppData\Roaming\EW4App\EW4App\4.0.0.0 and deleting any XML files whose name starts with 'TrignoSettings'. There may be more than one.
 
Restart the Control Utility and it should start normally.
