    Hello KHenseler,

    The var dir is in different place than you wrote:


    Probably this file was missing:


    it’s executable which uninstall NoMachine.

    Could you install again !M and send to forum[at]nomachine[dot]com:

    1) An installation log file:


    if the file is missing please find the newest:

    C:\Users\YOUR_USERNAME\AppData\Local\Temp\Setup Log 2024….

    2) An uninstall log file:

    Run cmd as Administrator, and in cmd run:

    "C:\ProgramData\NoMachine\var\uninstall\unins000.exe" /LOG="C:\Users\YOUR_USERNAME\Desktop\NMuninstall.log"

    after uninstallation process closes, please send from your Desktop NMuninstall.log.

    Do you have NoMachine enterprise client installed parallel with
    NoMachine server package?


    Hello Nohar,

    Is it possible to send to us screenshots of errors boxes:

    “Application Error, The application was unable to start correctly

    is there nxserver.bin mentioned?

    Could you also firstly change a configuration key in “C:\Program
    Files\NoMachine\etc\server.cfg” from:

    #SessionLogLevel 6


    SessionLogLevel 8

    Then press win to open the start menu. Type in cmd to search for
    Command Prompt. Press ctrl+shift+enter to launch Command Prompt as
    administrator. In cmd run commands in this order:

    sc query nxservice
    "C:\Program Files\NoMachine\bin\nxserver.exe" --status
    "C:\Program Files\NoMachine\bin\nxserver.exe" --version
    "C:\Program Files\NoMachine\bin\nxserver.exe" --restart

    in reply to: Uninstall on macOS not complete #46964

    Hi Danchirillo,

    We weren’t able to reproduce the problem. Looks like uninstall scripts
    wasn’t run.
    In which way did you uninstall NoMachine:
    1) moved to trash bin,
    2) removed /Applications/ dir from terminal,
    3) removed /Applications/ dir from SSH session?

    Did you see message boxes requested password and administrative
    privileges for NoMachine Uninstall (screenshots attached)?

    Do you still have /Library/Application Support/NoMachine/var/log. If
    yes, could you pack the dir and send to forum[at]nomachine[dot]com?

    Could you send also output from commands:

    which bash

    ls -l /bin/bash

    id nx

    Hello RedBoss,

    Could you let us know which local policies were missing?
    Do you also use Active Directory?

    in reply to: Installation on Macos 14 Sonoma problems #46829


    We weren’t able to reproduce the problem on MacOS 14. Could you collect logs
    like it is described in:

    and send to forum[at]nomachine[dot]com.

    From which version did you do upgrade of MacOS?
    Do you know which version you had installed before NoMachine update?

    A possible solution can be approving NoMachine mandatory security permissions:
    – Screen Recording,
    – Accessibility.

    in reply to: No folder in Application Support #46541


    In your first post you reported lack of:

    /Library/Application Support/NoMachine

    In the directory there are NoMachine installation logs. Because of missing
    log dir I asked you about system installation logs:


    Now you confirmed that you have /Library/Application Support/NoMachine
    and you sent NoMachine nxinstall.log. In the log file I couldn’t find reason
    of your problems. Please send another pack of logs as it’s described in:

    A possible solution can be approving NoMachine mandatory security permissions:
    – Screen Recording,
    – Accessibility.

    Helpful will be full set of logs, you can pack whole log directory:


    usually – C:\ProgramData\NoMachine\var\log

    You can send it to forum[at]nomachine[dot]com. If it’s possible you can also
    send screenshots of the errors.

    Is it x32 or x64 operating system? Which version do you use now?
    Did the problem happen before or on previous versions everything was ok?

    Hello Luca,

    we would need some additional information, could you please send to us part of system installation log?

    The path to the file is:


    You can send us the whole file or just the part related to NoMachine.
    The NoMachine part starts from line:

    Installer[63841]: NoMachine  Installation Log

    and ends:

    Alternatively during installation you can call log window by clicking Command + L (⌘L). In the installer log window choose:

    Show All Logs‘ and after that ‘Save‘.

    Please send the file with installation logs to forum[at]nomachine[dot]com.

    in reply to: Cannot install NoMachine from deb or tar #43557

    Hello Mysticle31,

    It looks like you have a problem with installation directory permissions /usr.
    They should look more or less like:

    drwxr-xr-x. 13 root root 226 Mar 22 14:16 usr

    in reply to: NoMachine default install fails on Windows 11 #43535


    This looks like an issue we already discovered when Firefox is in use.
    The described behaviour is strictly related to how Firefox handles
    the executable, in particular we found that it sets the ‘PreferSystem32Images’
    flag before running the .exe application.

    Do you use Firefox to directly run installation? Here is a related article:

    in reply to: Removing NX User from MacOS Ventura Lock Screen #43452


    Unfortunately in the logs package there is missing nxinstall.log. The log file tell us more what happened wrong
    during installation. But now you have hidden user nx. We cannot disable “Other Users” option in NoMachine
    installation process but you can do it yourself by using command in your terminal. To disable “Other Users”
    option please type:

    sudo defaults write /Library/Preferences/ SHOWOTHERUSERS_MANAGED -bool FALSE

    If you want to enable it back use:
    sudo defaults write /Library/Preferences/ SHOWOTHERUSERS_MANAGED -bool TRUE

    in reply to: Removing NX User from MacOS Ventura Lock Screen #43297

    Hello Nairb,

    Is it fresh installation of NoMachine?

    Did you do a MacOS update last time?

    Could you create a compressed tar.gz archive of the
    /Library/Application Support/NoMachine/var/log directory
    and send to forum[at]nomachine[dot]com.

    Please also check output of this command:
    defaults read /Library/Preferences/ HiddenUsersList | grep nx

    Anyway you can try to hide the user by running;

    sudo /usr/bin/defaults write /Library/Preferences/ HiddenUsersList -array-add nx



    We need more info, could you prepare log package as is described in:

    Pls run this commands one after another:

    1. /etc/NX/nxserver --version

    2. sudo /etc/NX/nxserver --shutdown

    3. ps -efja | grep nx

    4. sudo systemctl start nxserver

    5. systemctl status nxserver

    6. ps -efja | grep nx

    and send output, the logs package to forum[at]nomachine[dot]com.

    Which distribution of Linux do you use?

    in reply to: Cannot create the home directory for the nx user #39808

    Hello McVitas,

    Looks like you have a problem with creating a profile of user nx.
    There are 2 possible reason:

    1. Do you use domain users/LDAP/ActiveDirectory? Do you have non
    standard restrictions for users?

    2. It’s possible that default user profile on your host might be
    corrupted. You can try to create few user accounts and check if
    it’s possible to login on their desktops. If you experience any
    problems, please refer to this Stack Overflow thread:
