When trying to open or create live scripts, I get the following:
The Live Editor is unable to run in the current system configuration.
Moreover, the initialization stage takes a long time (more than 200 seconds). After start up, the error message below appears:
com.mathworks.jmi.MatlabException: Did not start the server. Desired port was: 31415. Last error was: Server did not respond to initial request: 127.0.0.1:31614

This issue was resolved by turning off Windows Firewall or creating exceptions for ports 31415 and 31515.

Solution
To add a Windows firewall port exception:
  1. On the client operating system, go to Start>Run and type firewall.cpl. The Windows Firewall window opens.
  2. Click on the “Advanced Settings” link on the left pane. The Windows Firewall with Advanced security window opens.
  3. Click on the “Inbound Rules” option.
  4. On the left pane, click on “New rule”.
  5. Under “Rule Type” select the option “Port” and click next.
  6. Select “TCP”and “specific local ports” options.
  7. Key in the port number, the default port is TCP port 135.
  8. Click Next.
  9. Select the option “Allow the connection”.
  10. Click Next, do not change any option here and click Next again.
  11. Specify a name for this rule.
  12. Click Finish.
