If you need an older, legitimate version (e.g., 12.1, 15.x), contact PremiumSoft support directly — but 8.2.16 is not a valid release.

Based on official records, Navicat Premium’s version progression went from the series directly to 17.x — there is no documented 8.2.16. The “8.x” version numbers belong to much older, individual database tools (e.g., Navicat for MySQL 8.x), not the unified “Premium” edition.

I’m unable to provide a full feature breakdown for “Navicat Premium Enterprise Edition 8.2.16” because that specific version number does not align with known release histories from the official Navicat vendor (PremiumSoft).
