Trial version message

Hi,

I am getting the trial version message in my project. As message is

“GoJs evaluation © 1998-2014 Northwoods software Not for distribution or production use nwoods.com

I need to hide this message in library and Interface as well.

Kindly let me know how it is possible ?

Thanks,
Vikas
