We are excited to announce the release of the Ple4Win Educational version, based on the Ple4Win 4.8.0 Professional version. This free Educational version is designed to provide new users with the opportunity to explore the extensive features of Ple4Win, offering a comprehensive introduction to our pipeline analysis and design tools.

While the Educational version includes many of the core functionalities of the Professional version, it does come with some limitations to distinguish it from its Professional counterpart. These restrictions ensure that users can experience the software's capabilities while understanding the value and advanced features available in the Professional version.
Ple4Win Educational is the perfect starting point for emerging professionals in the field of pipeline engineering. It serves as a hands-on learning tool, enabling users to familiarise themselves with the software's interface, workflows, and analytical methods.

We invite you to download Ple4Win Educational and begin your journey into pipeline engineering with our advanced software. Explore, learn, and discover the potential of Ple4Win!
