Error NullReferenceException: Object reference not set to an instance of an object

Hi, I am new to Unity 3d and game making.. not a programmer.. going to use Bolt.. After Downloading and Installing Unity 3d and downloading Bolt from Asset store.. tried to install it and get this error..

1)
Missing unit options.
Create them with 'Tools > Bolt > Unit Options Wizard...'.
