NXPowerLite can be installed on a per-machine basis such as a Terminal Server, but it does mean that it is your responsibility to ensure that you have enough licenses to cover all the users that have access to NXPowerLite through the machine or terminal service.
One registration key is all that is required to install and register NXPowerLite Desktop on a terminal server for use with multiple users. Multiple licenses are available to purchase through our web store.
If you need to ensure that only a subset of users/Terminal Server users have access to NXPowerLite and you are using Windows Server or Windows 7/10 then we recommend the built-in AppLocker feature.
