Correct, QuartusII Web 13.0sp1 is the last and now only available version of Quartus that supports the CycloneII family.
I run it on my current Windows 10 system and it works just fine. It also works on Windows7 64b. And there is a linux version also.
Any later version of Quartus like 16, 17, 18, etc does not support CycloneII.
