Let’s address the elephant in the lab: Zview 3.2b is abandonware in practice, but not in law. Scribner Associates continues to sell licenses for later versions. If your research leads to a high-impact publication (e.g., Nature, J. Electrochem. Soc.), the journal may request proof of software licensing. Several papers have been delayed because authors could not produce a valid license for Zview 3.2b.
Recommendation: If you are starting a new project, download a trial of ZView 4 (Scribner’s current version) or use open-source alternatives. The 20+ year old codec in 3.2b may also produce fitting results that are less accurate for complex systems (e.g., solid-state batteries with distribution of relaxation times). Zview 3.2b Download
If you must use 3.2b for legacy data, install it on an offline, air-gapped PC dedicated to your impedance spectrometer. Never connect that PC to the internet. This protects you from both security risks and accidental license violations. Let’s address the elephant in the lab: Zview 3
