✅ You run a legacy Fiery server (FS100–FS150 Pro) on Windows 10 or older macOS, and you need a reliable, free, and familiar tool without an internet connection.
If you must use 5.6 for an old server, install it on a dedicated offline Windows 10 VM to avoid security risks from unsupported software. For production safety, migrating to a newer Fiery server and CWS 6.x is highly recommended. Download safety note: Do not download CWS 5.6 from random file-sharing sites. Keygens or cracks may contain malware. Use only manufacturer‑provided links or your original media.
❌ You have a newer Fiery (FS200+), use Apple Silicon Mac, or require modern imposition features like dynamic nesting or variable data previews. In that case, get CWS 6.5+ (free download from EFI’s site).
