Download Option 2: DVD .iso File

If you do not have Internet access or if you require a DVD, you can download and use the DVD ISO file to create your own installation DVD for installing Altera's software and device support. You must first install the Altera Complete Design Suite (ACDS) software (Windows or Linux version) before you install the ACDS Devices software. You must install both the ACDS software (Windows or Linux version) and the ACDS Devices software.
