According to Download Center(Altera Website), the Web Edition is supposed to support all MAX family. However, when I compiled my project under this version, "Error: Unsupported family: MAX II." occurs.
Just a guess: did you install MAX II support when you installed Quartus? At one point during installation you should be faced with a list of tick boxes where you can select which devices you want to support. Run the "Modify Altera Complete Design Suite" executable to change which devices your installation supports
Of course, I did. If did not select MAX II, I should not be able to open a project with MAXII since uninstalled devices are not appear on the device selection list when making a new project.
I think I need some configuration, but I do not know.;
