I am having issues downloading Quartus Prime Pro. When I click the download link, it takes me to a login page. If I type in the wrong username/password, it says "wrong username/password". If I type in the correct username/password, it takes me to https://fpgasoftware.intel.com/saml_login/?acs with the message "Errors: invalid_response" and then some funky web codes: "samlNameId: None samlSessionIndex: None". I tried multiple browsers.
Sorry for what you had been facing up until today, our INTEL IT developers are still actively working on this fix. I will try to push them to get this fixed as soon as possible.
May I know what specific version that you were trying to download?
Another weird issue: After installing quartus prime pro, I get a popup asking for a license. I select "Connect to Altera Self-Service Licensing Center" and all it did was open a browser to the www.intel.com home page.
Quartus Prime Pro require license, the page should connect to https://www.intel.com/content/www/us/en/programmable/b/self-service-licensing-center.html
Since you do not have the license, you will need to purchase the Quartus license in https://www.intel.com/content/www/us/en/programmable/buy/design-software.html
