Versions of Quartus below 17.0 (except for 13.0sp1/13.1) have all been deprecated by Intel and are no longer available online.
You have to contact an Intel sales rep and plead your case for why you need special access, sign an NDA, and maybe they will give you a download link. Not guaranteed.
What is the reason you need such an early version, can you elaborate?
Thanks for update answer @ak6dn. We have not heard from you, if you don’t have any further question, I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.
