I download the Quartus prime lite edition in 09/12/2019 because it said it's free while the Pro and Standard version need charge. When I open this software today it said my software licence is going to expire in 5 days and asked me to pay for it.
I don't know why the FREE version also need me to pay for it.
I already click the ignore and don't show again button so the notice can't appear again. I remember the information in that notice is "maintenance subscription for the quartus prime software expires in 5 days, in order to be eligible for renewal pricing you must renew your maintenance subscription before it expires, renewing your maintenance subscription ensures that you can download updates……" and there are two button in the bottom, one is "buy now" another is "ignore" or "close". If click "buy now", you will be introduced to this website:"https://www.intel.com/content/www/us/en/programmable/buy/design-software.html".
I search the post in this community and find some other guys also have similar porblem like me (see: https://forums.intel.com/s/question/0D50P00003yyT29SAE/quartus-prime-lite-160-license-renewal-), but they said the quartus still works even after the expiration date, if so, I think it's okay for me.
Seven days past, I still can open the Quartus software and check my project, but I didn't try building any project yet, maybe the function is still okay. If there is any other problem, I might download Quartus Prime Lite edition again.
