Version 4 or later offer automatic updates so that all users can keep their NoMachine installations up-to-date with the latest patches and releases.

Alternatively, customers of the pay-for products can download updates from their dedicated account in the Customer Area. Once you have logged in, you can find the links to the available updates for the software that you have a valid license for. This way there will be no confusion as to what you should be downloading.

To manually install updated, please refer to the instructions that you can find in the associated release announcement or the installation guides:

Registered users of any of the NoMachine for the Enterprise products will be able to continue to receive automatic updates, or use the manual update procedure, for the duration of the license (generally, one year).
