I am having the same type of problem. I have a licensed version 23.0 for WinZip that I have installed. My Licensed version of KIS is 20.0.14.1085 (g). My licensed Windows version is Windows 10, Version 1903 (OS Build 18362.535). I have turned off Software Updater in KIS. I have gone into WinZip Options → Settings → Updates & set that as “Do Not Check for Updates”. I also went intoi RegEdit & updated both HKEY_CURRENT_USER\Software\Nico Mak Computing\WinZip\UpdateCheck & HKEY_LOCAL_MACHINE\SOFTWARE\Nico Mak Computing\WinZip\UpdateCheck and set AutoMode - to “0” & NoUpdateChecking - to “1” per online instructions I found that is supposed to disable the updater completely. None of it seems to work as *EVERY SINGLE DAY* the licensed version 23.0 is uninstalled & a (expired) trial version 24.0 is installed in it’s place, which can’t be used since the trial period is expired. I checked C:\ProgramData\Kaspersky Lab\AVP20.0.0\Data\patchmanagement\download_storage' & the folder is empty. I get no prompt to update WinZip. I uninstall WinZip 24.0 & reinstall licenced version 23.0 anywhere between 5 pm and 10 pm one night & at some point before 9 pm the next day, Version 23.0 is gone & trail version 24.0 is installed. It has happened pretty much daily for the last 2 weeks, possibly longer than that. I can’t tell if it is KIS that is doing ir, Windows (somehow) is doing it or WinZip itself that is ignoring its settings & doing it, but I am tired of it. I have also put in a ticket with WinZip support about the issue. I need to figure out which program is causing this and a fix for it because it is ridiculous to have to uninstall and reinstall a program daily just to be able to use the older version that I paid for a license for.
