Labcenter Electronics never released an official portable version.
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.
However, for the modern engineer or serious learner, the risks (security, legal, and functional) outweigh the convenience. The world has moved to web-based simulators and open-source EDA tools that are equally portable, infinitely safer, and completely free.
