How to Download and Install Visual Prolog 7.4 for Free

Visual Prolog is a logical programming language that allows you to create industrial applications for Windows platforms. It supports algebraic data types, fully integrated fact databases, automatic memory management and parametric polymorphism[^1^]. If you want to learn more about Visual Prolog, you can check out this book[^4^] that covers the main features and concepts of the language.

However, Visual Prolog is not a free software. You need to purchase a license to use it for commercial purposes. The latest version of Visual Prolog is 10.0.1002[^1^], which costs $199 for a personal edition and $999 for a professional edition[^1^]. If you are looking for a cheaper or free alternative, you might be tempted to download a cracked version of Visual Prolog 7.4 from some shady websites.

But beware! Downloading and installing cracked software is illegal and risky. You might end up with malware, viruses, spyware or ransomware on your computer. You might also face legal consequences for violating the intellectual property rights of the software developer. Moreover, you will not get any updates, support or bug fixes from the official source.

So, what can you do if you want to try Visual Prolog without paying a fortune? Well, there is a solution. You can download and install a free trial version of Visual Prolog 7.4 from the official website[^1^]. The trial version has some limitations, such as a maximum of 1000 clauses per project and no access to some advanced features[^1^]. But it is enough to get started with the language and learn the basics.

Here are the steps to download and install Visual Prolog 7.4 for free:

  • Save the file "vip74pe.exe" on your computer and run it.

  • Follow the instructions on the screen to complete the installation process.

  • Launch Visual Prolog from the Start menu or the desktop shortcut.

  • Enjoy your free trial of Visual Prolog 7.4!

I hope this article was helpful and informative. If you have any questions or comments, please feel free to leave them below.If you want to continue the article, you might want to add some examples of Visual Prolog code and explain how it works. You might also want to compare Visual Prolog with other logical programming languages, such as Prolog or SWI-Prolog. You might also want to mention some applications or projects that use Visual Prolog.

Here is a possible continuation of the article:

Visual Prolog is based on the standard Prolog language, but it has some extensions and differences. For example, Visual Prolog supports object-oriented programming, which allows you to define classes and methods for your data types. Visual Prolog also has a graphical user interface (GUI) library, which lets you create windows, menus, dialogs and other graphical elements for your applications.

Here is a simple example of Visual Prolog code that defines a class called person and creates an instance of it:

class person


name : string

age : integer

end properties


constructor : (string Name, integer Age).

sayHello : ().


constructor(Name, Age) :-

name := Name,

age := Age.

sayHello() :-

stdio::writef("Hello, my name is % and I am % years old.\n", name, age).

end class


person = person(string Name, integer Age).


run() :-

P = person("Alice", 25),


This code defines a class called person with two properties: name and age. It also defines two predicates: constructor and sayHello. The constructor predicate initializes the properties with the given arguments. The sayHello predicate prints a greeting message using the properties. The domains section defines a domain called person that is equivalent to the class person. The clauses section defines a predicate called run that creates an instance of person and calls its sayHello method.

If you run this code in Visual Prolog, you will see the following output:

Hello, my name is Alice and I am 25 years old.

As you can see, Visual Prolog allows you to write concise and readable code that combines logic and object-oriented programming.

Visual Prolog is not the only logical programming language available. There are other variants of Prolog, such as SWI-Prolog, GNU Prolog, Strawberry Prolog and more. Each of them has its own features and advantages. For example, SWI-Prolog is widely used for research and education purposes. It has a large library of modules that support various tasks, such as web development, natural language processing, artificial intelligence and more. GNU Prolog is a free Prolog compiler that supports constraint solving over finite domains. It can generate stand-alone executables that run on different platforms. Strawberry Prolog is specially designed for education. It has a graphical interface that allows you to create and debug Prolog programs easily.

Visual Prolog is one of the most powerful and type-safe logical programming languages. It can be used for creating industrial applications that require complex logic and data processing. Some examples of applications that use Visual Prolog are:

  • Expert systems: These are systems that provide advice or solutions based on a set of rules and facts. For example, Visual Expert is an expert system shell that allows you to create your own expert systems using Visual Prolog.

  • Artificial intelligence: These are systems that simulate human intelligence or behavior. For example, Amzi! Adventure is an interactive fiction game that uses natural language processing and logic programming to create a rich and immersive story.

  • Data analysis: These are systems that process and interpret large amounts of data. For example, DataFlex is a data analysis tool that uses Visual Prolog to perform queries and calculations on various data sources.

In conclusion, Visual Prolog is a logical programming language that offers many benefits for developing industrial applications. However, it is not a free software and you need to purchase a license to use it legally. If you want to try it for free, you can download and install a trial version from the official website. You can also learn more about Visual Prolog from books, tutorials and online resources. 0efd9a6b88
