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.
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. Navicat Premium Enterprise Edition 8.2.16
