• Open an elevated command prompt
  • Click the Start Menu and start to type cmd
  • You should see “Command Prompt” Right-click it and choose Run as administrator
  • Choose Yes on any User Account Control messages that might appear.
  • In the command prompt type the following: (using notepad to edit the network.lic file)

cd C:\Program Files\MATLAB\R2019a\licenses
notepad network.lic

• Verify that the file contains the following and if it doesn't, update the file and save it.
