Reason 10 Upgrade with ProTools HD 2018

Recently tried to upgrade from Reason 6.5 to Reason 10. Downloaded (as upgrade) successfully, but when I go to find in ProTools, it only sees the old version Reason and (6.5) not the new one (10). I have already tried deleting “installedAAXplugins” from PT prefs in libraries.

Is there more to upgrading from 6.5 to 10 than I am doing? Seems like an upgrade should be more intuitive than this..

Do I need to Uninstall 6.5? Is there a suggested way to do that?

Impossible to get Propellerhead on phone. And they respond to emails in brief after 5-7 day delays.. Any help appreciate!
