  I have a problem. After downloading OptiSystem Free 30 Days and installing it, I get the following message:
  License unavailable.
  Error #SH203: License not available [41]
  License expired
  .
  First, I downloaded the program before with my university account, then the 30 days expired, so I took another university account from a friend of mine and registered with it on the website and downloaded Optisystem again. After uninstalling the expired version and installing the new one, this message still appears:
  License unavailable.
  Error #SH203: License not available [41]
  License expired

  Hello,
  
  Thanks for reaching out to us!
  
  Unfortunately, we do not allow to try multiple free-evaluations on the same PC. It’s limited to only one machine. You can try to download the installer file on another PC and it should work fine.
  
  Also, If you need OptiSystem for longer duration to complete your project, then I urge you to lease the license (for 1 year) or apply for the student license, which are at subsidized rates. Let me know if you need further assistance with it?
  
  I hope this was helpful?
  
  Warm Regards,
  Saurabh Bedi.
