Important Notices

Customers of Enterprise Cloud Server Cluster v8 who wish to upgrade to v9 should refer to the instructions at: https://www.nomachine.com/AR11V01257. 'Online' subscriptions v9 for the enterprise products require a NoMachine server v9 and are not compatible with servers v8 or earlier. Please do not hesitate to contact us via any of the available channels for assistance.

All NoMachine Enterprise software for evaluation can now be activated using a license file which is generated from the User Area and activated online.  For further instructions, users can consult the following article https://kb.nomachine.com/AR10K00713.

The RPM packages are now built using a more recent version of RPM in order to support also SHA256 digest and to allow signature verification on recent RPM-based systems. On old OS versions like Open SUSE 11.2 and earlier, it will be necessary to install NoMachine tar.gz packages.

The current version doesn't provide full support for Wayland-native virtual desktops as required by adopting GNOME 49, a possible temporary solution is to downgrade GNOME or adopt a lightweight desktop. More details are available here: https://kb.nomachine.com/AR10W01330
