Typical upgrade workflow (V6.1 → V6.2):
If upgrading from a very old version (e.g., V5.x), you may need an intermediate upgrade (V5→V6.1→V6.2) with separate reference numbers.
If you are using a Magelis HMI (e.g., STU, XBT-GT, XBT-GK series), the internal firmware may need an update to support Vijeo Designer 6.2 features. This is done via a System Card or Firmware Update. vijeo designer 6.2 upgrade reference number
Schneider Electric uses specific "Reference Numbers" (Order Codes) to identify software products. For Vijeo Designer 6.2, the numbers differ based on whether you are buying a full package or an upgrade, and whether you use a physical dongle or a software license.
Important Note: Vijeo Designer 6.2 is often sold as part of the SoMachine or SoMachine Basic suite, or as a standalone HMI configuration tool. Typical upgrade workflow (V6
During testing, an anomaly was discovered: using reference VJDSND62-UPG-01 on a machine that previously had a demo license (expired) triggered a silent rollback—the installer completed without errors, but the HMI runtime compiler remained at v6.1.
Root Cause: The upgrade reference number checks for a valid, non-expired base license checksum in the Windows Registry. If absent, it installs only the IDE (Integrated Development Environment) but not the new firmware packager. Input the reference number → system requests a
Workaround: Manually delete registry key HKLM\SOFTWARE\Schneider Electric\Vijeo Designer\6.1\LicenseStatus before running the upgrade installer with the URN.
