Questions about C2000 tutorial, cannot find library.

When I am trying to use the tutorial example, the error message occurs like this :

Unable to find library component ‘TIC2000_Lib/Digital Out’ referenced by component ‘<hidden component>’.

Should I get an RT-BOX license before I use the C-script 000 library ?

All demos in the TI C2000 Target Support Demo Model Library use the PLECS RT Box to perform hardware-in-the-loop testing of the generated embedded code. Therefore, the PLECS RT Box Target Support Package should be installed and configured to access components from the RT Box Target Support Library. The RT Box Target Support Package can be downloaded from https://www.plexim.com/download/rt_box.

The PLECS RT Box hardware is not required to generate and run microcontroller (MCU) code or to run the demo models offline in PLECS Blockset and Standalone.
