The following paper provides a technical overview of how software licensing works within the Pro-face GP-Pro EX (formerly WinGP) environment. It is intended for educational and system maintenance purposes only. It does not provide, nor does it encourage the use of, unauthorized key codes, cracks, or keygens. Using unauthorized software in industrial environments poses significant safety, security, and liability risks. Technical White Paper: Software Licensing and Key Code Management in Pro-face HMI Systems Abstract In industrial automation, Human-Machine Interfaces (HMIs) serve as the critical bridge between operators and machinery. Pro-face, a leading manufacturer of HMI hardware and software, utilizes a licensing system involving specific "key codes" to activate their runtime software, historically known as WinGP and currently integrated into the GP-Pro EX suite. This paper explores the technical architecture of the Pro-face licensing model, the function of key codes, the evolution from physical dongles to software activation, and best practices for license management in industrial settings. 1. Introduction Pro-face (a brand of Schneider Electric) is renowned for its HMI solutions. The software used to develop and run applications on these units is GP-Pro EX . Within the context of the software's runtime environment—often referred to as WinGP (the PC-based runtime version of the HMI software)—the term "key code" refers to the alphanumeric string required to activate the software license.
