You are starting a new design, have modern Cyclone IV/V/10 or MAX 10 chips, or want security and support. Use Intel Quartus Prime Lite instead.

Download the Quartus II 8.1 Web Edition executable for Windows. It is highly recommended to also download the corresponding Service Pack (SP1) , as it fixes known bugs. Install Quartus: Run the installer and follow the prompts.

The primary reason for utilizing Quartus II 8.1 today is hardware obsolescence. Newer versions of Intel Quartus Prime have completely dropped support for older chips like the Cyclone II or MAX 7000 CPLDs to reduce software bloating. For educational institutions utilizing older laboratory development boards, or engineers maintaining legacy industrial equipment, keeping a functional copy of Quartus II 8.1 is essential for compiling modifications and troubleshooting existing hardware implementations without redesigning the entire physical system.
