I got Windows 7 and MATLAB worked fine but after updating to Windows 10 this issue is happening
Steps:
  • I launch Matlab R2019a and it prompts an license activation window.
  • I fill "Enter the full path to your license file, including the file name" with C:\Users\XXXXXX\AppData\Roaming\MathWorks\MATLAB\R2019a_licenses\license_XXXXXX-PC_#######_R2019a.lic where ###### is my license number.
  • I got an "Activation is complete" message
  • After this, Matlab doesn't launch automatically
  • I launch it manually again and i go to the first step where MATLAB requires me again a license activation when I've already got an "Activation is complete" message
Thanks in advance. Ask for more detailed information if needed
