zyhParticipantIf you wish to continue using the 9.3 version of NoMachine, do you need to pay for it? If you want to continue using the free version, what should you do?

BritgirlKeymasterHi,
the Enterprise Desktop product you installed, like all products in the Enterprise suite, is available as an evaluation version for a period of 30 days. The message you see simply means that your evaluation subscription is expired.
If you want to continue using NoMachine software for free, you can still uninstall the Enterprise Desktop package, and install the free edition on the machine you want to reach. Using it is completely free and does not require a server-side subscription.

You can compare the two products at the following link: https://www.nomachine.com/everybody/nomachine-for-your-os

zyhParticipantbut I have repeated these operations many times: uninstalling, installing the free version (https://download.nomachine.com/download/?id=3&platform=windows), and attempting to connect. But it still shows the same error.

BritgirlKeymasterDid you reboot the Windows machine?
On the Windows machine, go to Settings > ServerĀ > Updates and take a screenshot, and attach it using the upload attachment tool.
