If you decide to explore the old version, do so inside an with no sensitive data. But if you want to build a career in electronics, invest your time in learning KiCad, LTspice, or the official Proteus 8/9.
In the world of Electronic Design Automation (EDA), few names resonate as deeply with hobbyists, students, and engineering professionals as Proteus . Developed by Labcenter Electronics, Proteus has been the gold standard for simulating microcontroller-based circuits, particularly because of its unique ability to simulate real-time firmware alongside analog/digital components.
