Consider using EcoStruxure Machine Expert (the modern replacement), which has a free 30-day trial with no dongle required. It can often open SoMachine 3.1 projects.
SoMachine 3.1 is not the same as SoMachine Basic (for M200 series) or SoMachine Motion (dedicated motion controller version). Ensure you need the full SoMachine 3.1 suite.
: The primary way to get legitimate legacy software is through the Schneider Electric Global Download Center download somachine 3.1

This article explains everything you need to know: where to find the official download, system requirements, installation steps, common pitfalls, and how to legally access the software today. Ensure you need the full SoMachine 3
The most important advice: Malicious code in PLC programming environments can destroy machinery, steal intellectual property, or introduce ransomware into OT networks.
: If you are using M221 logic controllers, you likely need SoMachine Basic (now EcoStruxure Machine Expert - Basic), which is free to download. An operating guide for this version is available for technical reference . What are the System Requirements for SoMachine v3.1 The most important advice: Malicious code in PLC
: It combines PLC programming and HMI development (via Vijeo Designer) into a single environment, saving significant engineering time. Hardware Compatibility : It is specifically designed for the logic controllers. Industrial Monitor Direct Critical Migration Note
