I understand your concern and will do my best to help you resolve the issue.
Please confirm if you have both these operating systems on one computer?
Follow the steps below to do a manual cleanup of CC from your machine:
Step 1: Disable all the security software’s installed on your machine, example: Firewall, anti-virus, internet security, system optimizer, browser security add-ons.

Thank you for the further troubleshooting steps. Could not fathom completely deleting Lr from my machine. I was able to update it via hotspot on phone and other wifi, although this is only an Adobe thing. Also, I recently received a new download link from support that as well stated there were/are known issues with downloads and installs. Thank you.
