Thank you for your reply.
Doing what I think the KB suggested, I; (1) verified my user account is an Admin with full rights to the specified directory, and (2) modified the specified directory and un-selected 'read-only'.
Then I rebooted and attempted the installation again. This resulted in the exact same error, "Installer Failed to Initialize"
Then I ran the 'Adobe Creative Cloud Cleaner Tool' again, and here are the new results. Can you suggest a next step?
