C++, MINGW, and user privileges

Hi all,
I’m trying to code some basic c++ on ATOM IDE. I downloaded the MINGW c++ compiler and it has installed properly (I think) and I’ve added it to my variable path.

I’m trying to run a “Hello World!” example, but my cmd line errors and and says, “ACCESS DENIED.” I have tried to allow full control to my own user account, but when I get to the widows dialog box, it’s greyed out. It’s like un-editable.

Any ideas on how to proceed?
