What version of quartus should i download. I tried the 18.1 lite edition but the link is broken. http://fpgasoftware.intel.com/?edition=lite&language=en_US

Hi Emmauel,

These problems could happen due to maintenance or scheduled backups.

Try now it should work, if not refer the link below for direct download links for all 3 versions with the device files.
