• ✔ Proteus VSM (Simulation core)
• ✔ ARES (PCB Layout)

Pre-Installation Checklist

1. Disable Antivirus Temporarily – Real-time scanning (especially McAfee, Norton, Avast) can corrupt the library indexing during a full install. Disable until the first reboot.
2. Run as Administrator – The installer must write to C:\Program Files (x86)\Labcenter Electronics and modify system registry keys.
3. Close all Office applications – The Proteus VSM integration with Office (for BOM export) can cause file locking errors.
4. Ensure no previous versions exist – Uninstall any older Proteus (v7, v8) or newer (v10, v11) to avoid DLL conflicts.
