Hello KHenseler,

The var dir is in different place than you wrote:

C:\ProgramData\NoMachine\var\

Probably this file was missing:

C:\ProgramData\NoMachine\var\uninstall\unins000.exe

it’s executable which uninstall NoMachine.

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

1) An installation log file:

C:\ProgramData\NoMachine\var\log\nxinstall.log

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
(0xc0000005)”

is there nxserver.bin mentioned?

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

#SessionLogLevel 6

into:

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

"C:\Program Files\NoMachine\bin\nxserver.exe" --status

sc query nxservice

After that pleas send output or screenshots of these commands and also
the log folder like last time.

Hello Horseman67,

You need to grant Terminal.app ‘Full Disk Access’. Go to

‘System Settings’ -> ‘Privacy & Security’ -> ‘Full Disk Access’

and then reopen Terminal.app and run:

sudo sed -i -e
"s/^AcceptedAuthenticationMethods.*/AcceptedAuthenticationMethods
NX-private-keytest/"
/Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg

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 NoMachine.app to trash bin,
2) removed /Applications/NoMachine.app dir from terminal,
3) removed /Applications/NoMachine.app 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?

Hi,

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

https://kb.nomachine.com/DT07S00243?s=collect%20logs

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.

Hi,

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:

/var/log/install.log

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:

https://kb.nomachine.com/DT11R00182

Hi,

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

%PROGRAMDATA%\NoMachine\var\log

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:

/var/log/install.log

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:

Installer[63841]: PackageKit: Registered bundle file:///Applications/NoMachine.app/ for uid 501

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.

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

Hello,

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:

https://kb.nomachine.com/TR12T10715

and here you can track fixing the bug by Mozilla:

Hello,

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/com.apple.loginwindow SHOWOTHERUSERS_MANAGED -bool FALSE

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

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/com.apple.loginwindow HiddenUsersList | grep nx

Anyway you can try to hide the user by running;

sudo /usr/bin/defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add nx

[zaq]

Hello

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

https://kb.nomachine.com/DT10O00163#1.1

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?

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:
