First time using Horizon..help

Hey it’s my first time using Horizon, and I can’t seem to figure out why it won’t let me put the folder in my hdd drive, it does detect the drive and its contents but it says “Access to the path … Is denied.”

Yes, I have turned the User Account Control all the way down, I tried reinstalling but nothing worked. Looked in the Properties of the folder and unchecked the read only. But It still won’t accept the files.

I’d love to hear your opinions on what’s keeping horizon from accessing the files I want it to get.
