To run Wolfram using a network license, both the client machine and the license server must be on the network and MathLM must be running.
If you do not have a MathLM license server, you will need to activate your copy of Wolfram. Please see "Activating Products in Wolfram" for more information.
To Launch Wolfram
From a shell, type WolframNB and press Enter.
Alternatively, if you are using a modern desktop such as GNOME or KDE, an additional menu folder named Wolfram 15.0 has already been added to the desktop menu. Inside the folder, an item named Wolfram 15.0 can be clicked to launch the program. If you have multiple versions installed, older versions will appear here as well.
File associations have also been modified such that .nb files now associate with the most recently installed version of Wolfram.
