I keep getting an error trying to generate a legacy license for quartus. I am following an old textbook, which uses Quartus II 7.1 and would really like to work with this particular version.This is the URL I am trying to use to generate a legacy license. URL: https://www.altera.com/support/support-resources/download/licensing/lic-choose.html It takes my Mac address and asks for an email. Then, gives this (not very helpful) error: [h=2]Altera Software Subscription Licenses[/h]Sorry. There were errors encountered during the license generation. Please click here (https://www.altera.com/support/support-resources/download/licensing/lic-choose.html) to re-submit your request. --- Any help would be much appreciated. I tried contacting support but have not had a resolution yet.
