Schneider Electric uses Sentinel LDK protection. Cracked versions contain rootkits. Furthermore, Schneider offers a 30-day fully functional trial of the Advanced version directly on their site. Use the trial for your project, then buy a license if you need to deploy.
Looking at the page as of the latest updates, the file available is often the newest release (e.g., representing V2.0, Hotfix 7), or a newer major version like V2.1.1.47 . Do not be concerned if you do not see a “Version 13” file specifically. Instead, you should download the latest stable hotfixed version of V2.x because it will have the most bug fixes, security patches, and device support. If your specific legacy project requires the older “V13” (or V1.3) architecture, you will need to search the same download center using the search term “Vijeo Designer Basic V1.3” and select the appropriate file from the filtered results.
Many older industrial machines still use Magelis STO/STU panels. Maintenance personnel frequently need the software to modify existing applications.
Always prioritize security and legality in your professional toolkit. Reach out to your local distributor for the specific version you need, and you'll be well on your way to designing more efficient, intuitive, and reliable HMI solutions for your automation projects.
