CircuitMaker 2000 is often classified as "abandonware". While hobbyists still use it via community forums like EEVblog or Electronics Forums , it may require workarounds to run on modern Windows versions (e.g., using Wine on Linux or compatibility modes). Comparison: 2000 Edition vs. Modern Version CircuitMaker 2000 Altium CircuitMaker (Modern) Cost Paid (Discontinued) Free Licensing Serial Key required Free Account / Cloud-based Simulation Built-in SPICE simulation Simulation removed (focus on PCB) Layers Up to 16 signal + 16 plane layers Support None (Community only) Active community & updates

If you’re looking for the same spirit of community-driven design without the headache of finding old serial keys, Altium CircuitMaker is the official modern successor. Circuit Maker - It's Dead Jim! - EEVblog
