AVEVA System Platform 2017 is not officially supported on Windows 11. According to AVEVA’s compatibility documentation and support cases:
Windows 11 support starts with System Platform 2023 R2 SP1 and later versions. These releases are certified for Windows 11 Pro, Enterprise, and IoT Enterprise editions. [docs.aveva.com]
Older versions like System Platform 2017 (including Update 3) were designed for Windows 7/8.1/10 and certain Windows Server versions. There is no official certification for Windows 11, and AVEVA recommends upgrading to a newer version for full compatibility and support. [industrial...ftware.com], [knowledge....urcess.com]
Running 2017 on Windows 11 may work in some cases, but it is unsupported, meaning you could face issues with installation, runtime stability, and licensing. AVEVA tech support generally advises migration to at least System Platform 2020 or 2023 for Windows 11 environments. [knowledge....urcess.com], [knowledge....urcess.com]
