Provide your administrative credentials if requested to authorize the installation.

Step 1: Welcome to the installer! Click on Next to start the installation.

Step 2: Read and accept the License Agreement and click Next to go on.

Step 3: Click Next to proceed and please wait while Setup completes the installation … You can then select where to install NoMachine or let the default location as it is.

You can update your installation from our repositories. Just open the NoMachine User Interface from your Programs Menu, access the 'Settings' panel and click on 'Server preferences'. Go to the 'Updates' panel and click on the 'Check now' button.

NoMachine has the automatic check for updates enabled: it will periodically check our repositories (by default every two days) to verify if updates are available. In this case, NoMachine will prompt a dialog informing that a new version is available but it will never automatically update the current installation.

Checking for updates can be disabled from that dialog by selecting the 'Don't ask again for this version' option or in the Updates panel by unchecking the 'Automatically check for updates' option.

Detailed instructions for configuring the Automatic Updates are available in this separate document: https://www.nomachine.com/DT10O00149.

Alternatively, you may download the latest available package from the NoMachine web site and click on the executable file to launch Setup. As for the installation, Setup will guide you through all steps necessary for updating your installation.

On Windows 7, Vista and XP, click on the Start button and click to open the Control panel from the Start menu. Then access panel 'Programs and Features' or 'Add or Remove Programs', depending on your Windows version.

NoMachine comes with a graphical User Interface (UI) which lets you manage settings and configurations for the server (Settings -> Server) and for the client (Settings -> Player).

This means that you have an administrative user interface for the server from which you can for example configure privacy settings or perform updates. Server settings are grouped in sub-categories: Status, Ports, Security, Devices, Performance and Updates:

Fig. 4 - Settings -> Server

You have also an interface for configuring the client appearance behaviour when you connect to another computer. Also client settings are grouped into sub-categories: Input, Appearance, Transfers, Security and Folders:

Fig. 5 - Settings -> Player

The User Interface for server and settings are detailed in two separate guides available in the Documents section on the web site (https://www.nomachine.com/all-documents) in the Configuration section. They are respectively: https://www.nomachine.com/DT11R00180 and https://www.nomachine.com/DT11R00177.

TIP

Changing server settings requires to authenticate with a privileged user (administrator on Windows, 'sudo' user or root on Linux and macOS).

The Settings -> Server User Interface can be accessed also via the NoMachine (!M) icon in the system tray of your computer by clicking on 'Show server status'.

Fig. 6 - Click 'Show server status' from the !M monitor menu to access the server settings

The Status panel provides quick access to information like the IP of the host machine and the possibility to stop and restart the server. Click on any of the other items to open the correspondent panel and view or change settings.

Fig. 7 - The NoMachine Server Status panel

The Settings -> Server area in the User Interface (see Fig. 4) takes care of configuration of how NoMachine functions when it accepts in-coming connections from other remote computers. For example, starting the NoMachine services automatically when the machine is rebooted. Locking the physical screen of this host when someone is connected from remote or checking for automatic updates can be configured in the 'Security' panel and 'Updates' panel respectively.

There are specific tutorials showing users how to blank the screen of the host while somebody is connected from remote, or how to disable access to the computer (i.e. stop NoMachine services from accepting connections) available in the 'Tutorials' section here: https://www.nomachine.com/all-documents

As mentioned earlier, it is possible to configure the appearance of the NoMachine User Interface (e.g. change language, fonts, and even color). A quick tutorial is available here: https://www.nomachine.com/customizing-the-appearance-of-the-nomachine-user-interface.

Clicking on the !M shortcut icon on your desktop, or opening NoMachine from the Applications or Programs menu of your computer and entering Settings will open this interface to let you configure graphical elements, the language used and so on. Just click on Settings -> Player.

From there, of course you can also configure your connection: right mouse click on the connection icon and 'Edit connection'.

It's also possible to configure specific behaviour to be adopted when connecting to the remote host, such as using custom hot-keys and shortcuts which must be passed from the client side to the remote desktop. We recommend you take a look at the quick guide here: https://www.nomachine.com/DT11R00177.

There are a number of specific guides and tutorials available on the website which you can consult here:
https://www.nomachine.com/all-documents

When you are connected to the NoMachine desktop, it's possible to share devices like disks and printers, change view mode for the remote display (e.g. resize the remote desktop, full-screen etc ...), adjust display quality and performance or record desktop activities.

All of this and more can be done via the NoMachine menu panel inside the session. To open it, press ctrl+alt+0 inside the session or click on the page peel in the upper righ corner of the session.
