Previous studies on BIM interoperability (Smith, 2019) highlight that library version mismatch is the primary cause of model corruption when opening legacy files. Graphisoft’s official policy (archived 2015) states that libraries for versions prior to Archicad 15 are only available to active license holders via physical media. Unofficial websites claiming "Archicad 12 library free download" are typically outdated or malicious (CyberBIM Report, 2022).
