If a user who installs NoMachine Enterprise Client doesn't have administrator rights on the Windows machine, a Universally Unique Identifier (UUID of the installation won't be created).

As a workaround a UUID must be generated manually. For example on Windows - open a cmd, navigate to NoMachine Client installation directory (by default NoMachine folder is created in the home directory) and execute command:

`binnxkeygen.exe -u > etcuuid`
