Hi BXia,
Greetings, regards to the issues mention I can see duplicate of question in another thread with on-going discussion. (https://community.altera.com/discussions/nios-system/licensing-altera-com-never-worked/352270/replies/352401)
Hence would suggest to continue the discussion there to make it more streamline. Please do let us know if there is any concern.
We will continue to monitor this post for the next 5 days. If there are no further inquiries during this period, I will step back and allow the community to assist with any future follow-up questions.
Thank you for engaging with us!
Best regards,
Altera Technical Support
