Consider migrating your project to TIA Portal V17 or V19. Siemens provides a "Migration Tool" that automates 90% of the conversion. The benefit: you can download the latest version easily, get modern OS support (Windows 11), and access new features. The downside: you must update firmware on all hardware.
Totally Integrated Automation Portal (TIA Portal) by Siemens is the backbone of modern industrial automation.
