The Quartus web edition is asking me to renew the maintenance subscription, otherwise the license will expired. I filled out a form, and I received the file with extension ".dat". I followed the steps in the email where I got the license, but it did not work. The software does not take the license:
1) I downloaded the file to C:
2)I went to license setup in Quartus, and I specified the path where the file is.
3) I hit the ok button, but when I close the program and I open it again, the warning with the maintenance thing pops up again.
I have done this several times, and it does not work.
I need help.
