Visual Prolog Studio (VPS) objects were available free of charge for educational purposes for several years. We will keep VPS free of charge for current version of Visual Prolog (which is 5.2 in the moment of writing).
For more information about licensing of VPS for Visual Prolog V5.2 please click here
The licensing terms have been changed after introduction of VP Studio Shell, which replaced VP Studio Setup utility and has been integrated into Visual Prolog Development environment.
The price of VP Studio Shell for existing registred users of VP Studio Objects is $49.99 USD.
Note:
Registered user is the person, who:
Downloaded VP Studio Setup Utility
Received installation password by email from us
For new and unregistered users the price of VP Studio Shell is $79.99 USD.
What is inside VP Studio Shell package:
All sample projects come with pre-compiled OBJECT (*.OBJ) codes and necessary declarations (prolog sources) for VP Studio Objects and classes. You will be able to compile and test sample application, add new functionality, explore functionality of sample applications only.
If you like provided objects and classes functionality and would like to use them inside your application - there is one time fee of $19.95 USD per object (class).
This one-time fee will grant you royalty-free license for using selected class inside your application.
You may
not distribute VP Studio Shell classes Source and Object files.
Please contact
us directly if you wish so.
We are working now with VP Shell for new coming version of Visual Prolog and plan to have it available after official release of new Visual Prolog.
With new Visual Prolog coming soon we will offer more features and more consistent capsulated Visual Prolog sources.
