Not every Pro-face HMI is compatible with GP-Pro EX v4.09.450. Here is a quick reference: New communication drivers were added, including support for
A known vulnerability in the Pro-face Transfer Tool (used to deploy projects) was patched in this version, improving authentication protocols when downloading via USB or Ethernet.
This release focused on three main pillars: security, expanded connectivity, and modern OS compatibility. Security & File Management Enhanced Project Files : A new security-focused project format (
While newer versions like 4.09.500+ have since added features like Siemens TIA Portal V18 support, Ver. 4.09.450 remains a stable "gold standard" for users who need a baseline for Windows 11 compatibility without moving into the newer licensing models seen in version 5.0. It balances modern OS needs with the familiar workflow of the 4.0 series. For those looking to maintain their fleet, you can find the Update Modules Version Reverter
