This article applies to NoMachine 4 and later versions. If you wish to install any of the NoMachine packages without having any Windows dialogs shown during the installation, you can run the installation from command line and use the silent or verysilent switch.

How to install

From a CMD console:

• Move to the folder where you have downloaded the NoMachine package.
• Install the package by running:

  >nomachine-packageName_packageVersion.exe /silent

  or:

  >nomachine-packageName_packageVersion.exe /verysilent

  For example:
  >nomachine_7.4.1_1.exe /verysilent

• Installation is completed when you see your prompt back.
   
• Reboot the machine (it's necessary to complete the installation of the server, so if you are installing the nomachine-enterprise-client, you can omit this step):

  >shutdown /r /t 10 /c ” your comments here”

  You can find more information about how to use the remote shutdown tool here: http://support.microsoft.com/?kbid=317371
   

To specify a non-default installation directory, use:

nomachine-packageName_packageVersion.exe  /SILENT /DIR="X:Target_directory"

or:

nomachine-packageName_packageVersion.exe  /VERYSILENT /DIR="X:Target_directory"

For example:

nomachine_7.4.1_1.exe /SILENT /DIR="X:Target_directory"

or

nomachine_7.4.1_1.exe /VERYSILENT /DIR="X:Target_directory"

Note for Windows XP: the NoMachine server will not start until the machine is rebooted.

Skipping the installation of USB modules

Since NoMachine version 6.7.6, the setup procedure for Windows, when executed manually, accepts a command line option to skip the installation of NoMachine USB modules:

nomachine-packageName_packageVersion.exe /usbinstall="0" /silent 

or:

nomachine-packageName_packageVersion.exe /usbinstall="0" /verysilent

Next updates via command line will still require to specify the usbinstall=0 option to skip the installation of USB modules. If you don't specify it, the USB module will be installed.

Updates via package manager or NoMachine automatic software updates will install the USB module.

Skipping the installation of printers

Since NoMachine version 7.9.2, the setup procedure for Windows, when executed manually, accepts a command line option to skip the installation of printers:

nomachine-packageName_packageVersion.exe /printerinstall="0" /silent 

or:

nomachine-packageName_packageVersion.exe /printerinstall="0" /verysilent

Next updates via command line will still require to specify the printerinstall="0" option to skip the installation of printers. If you don't specify it, printers will be installed.

Updates via package manager or NoMachine automatic software updates will install printers.
