This article refers to the freely available 'NoMachine' package - free for personal use. If you are using an Enterprise product from NoMachine, please log in to your Customer Area and proceed to the 'Support Enquiries' section you can find there. The support team will be able to assist you.

Remember that you need two computers to run NoMachine: the one you are connecting from and the one you which to connect to.

NoMachine for Linux

If you are trying to install NoMachine on Linux, bear in mind that we tested the installation on thousands of machines with thousands of different desktop environments and Linux versions, but of course we can't guarantee that it will work on your computer, with your version of Linux. So, if you have a problem, try to post it on the forums, including all the information we list in "What to provide". What we strongly suggest is to be sure you removed all residuals of version 3 you had before, especially if they were NX installations not from NoMachine. We've seen NX installations from products using our open-source software failing to uninstall correctly and interfering every attempt of NoMachine to run on the same computer later.

NoMachine for Windows or Mac

If you are on Windows or Mac, the installation should be even more straightforward.

Most problems people report are connectivity problems due to the firewall or the antivirus installed on the machine accepting the connection, with the firewall or antivirus blocking access from another computer.
