When loading the Windows 11 upgrade, which gets to the Installing up to 36%, then messages me to Manually Uninstall Zemana antilogger which I could not find on my system, so what do I do now?

    Totally brilliant! After a year of trying all sorts of things to get this Windows update I have now been able to move to the latest version. Phoenix 360 was a part of System Mechanic that was never removed with uninstall, I've done it manually and BINGO the update doesn't stop and request that you manually remove Zemana! Thank you for this.

    Thanks Matthew, I'm glad this helped you too - thanks for letting me know.

    I struggled with this same issue when helping with an upgrade to Win 11. Got this message from the installer:

    zemana antilogger - Manually uninstall
    Uninstall this app now because it isn't compatible with windows 11
    Error code 0xc1900209

    The product did not appear to be installed, however there was a ZAM_Guard service running. I stopped and removed this and deleted the driver .sys file but the issue remained.

    I found this article

    https://answers.microsoft.com/en-us/windows/forum/all/windows-10-upgrade-cant-complete-due-to-error-some/59404919-d635-4e0c-9f54-bbc8fc24b843

    which shows how to locate a file that is blocking an upgrade. I followed the process and found that the process was blocked by ZAM.exe in ...Program Files (x86)\Phoenix360\MalwareKiller. It looks like this was lying around from an old installation of an app that was uninstalled a long time ago.

    Deleting this folder resolved the issue.

    You can try Nirsoft Regscanner and do a search for StopZilla (instead of zam.exe).

    Ok the regedit deletions I did appear to have worked, and the 22HC upgrade finally got pushed thru! Just woke up to check if they worked, and they did. Thanks for your assistance!
