I'm new to asking the community for help but this issue really has had me stumped for a few days now.. I've granted administrative permissions to my boot drive and have control of it and am an admin on my account i'm using to troubleshoot. When I try to install anything onto my 1TB HDD (D-Drive) it says I don't have permission to install it to my drive. All my other storage space is full so I need help asap. How can I grant full permission to install what I want on my drive?
