Software subscriptions are per target host and activate the server component in the NoMachine software running on the machine you want to reach. This means you must install a valid subscription key or license file on each target machine (the "server") that you or other users will connect to. For example, if you want to remotely access three different computers where you have installed Personal Edition software, you will need 3 NoMachine Personal Edition Subscriptions. 

Once the appropriate NoMachine package is installed and activated on the server machine, you'll be able to connect to it. On the device(s) you are connecting from, you can install the free NoMachine Player (aka Enterprise Client in earlier versions) if you prefer only a connection GUI. These devices are not counted, so you can install NoMachine client software on as many devices as you like. The player component is also integrated into all of the NoMachine server products for convenience. You can freely access the player component without having a subscription key or license in place.

If the server-side software you install supports web-based connections you can connect from your device just using its web-browser.
