The ‘Standard’ version has two operating modes – the full-scale and demonstrational.
Demonstrational mode has severe restrictions. Particularly, it does not include functionality related to data storing in files and data exchange operations via clipboard. However it is not an obstacle to become familiar with LTC via ready-made examples of LTC sets, filters, functions and other LTC facilities that are delivered with distribution kit.
To switch LTC into full-scale mode it is necessary to get a license file. Another way is to get for free a trial license that will expire in 30 days.
