Siemens has released numerous newer versions (7.4, 7.5, 8.0, and 8.1) with enhanced features, improved security, and better modern operating system support. If you are planning new projects, consider migrating to a more recent version that offers active support and compatibility with Windows 10/11.
Shut down the WinCC Runtime environment. Close WinCC Explorer, Step 7 / SIMATIC Manager, and any background Siemens services (such as the Automation License Manager).
