Answer 1

You will want to log into your my.presonus.com account and go to My Products>Software>Notion Conducting.  Here you can download the latest installer.  You do not need to authorize the software with the version that you download from your account.  If you have any problems, please click the "Support" tab from within your account and submit a support ticket.
