Hi, I am using Intel Quartus II Build 263 2012 Web Edition. I am getting a message about "Your maintenance subscription will end up in 30 days". What does it mean/have to do ? Does it affect my use of this SW ? Thanks in advance for help.

Hello

Welcome to INTEL forum. Web Edition software will continue working even after maintenance subscription expires. If error message appears, this is the normal behavior of the Web Edition software and you can ignore the message. Please continue with the compilations.
