Thank you for your feedback. Yes, indeed - generating ID and sending email don't work for Standard and One-click packages, and work for Agent only. We'll be checking this issue and fix it by the second beta coming soon.
Secondly, the version number for both the viewer and the host after install both indicate 18.104.22.168 (Host) and 22.214.171.124 (Viewer) rather than 6.5
That is correct. We are using 6.4.x.x as an interim version number until we make the final 6.5 release.
