Unable to point AMD to Halo 5

Hello, I’ve got an AMD card that I want to run Halo 5 with.
Problem is, is that for me to even get to the exe file, I had to mess around with permissions so I can see into the WindowsApps folder.
That being said, I can see in the folder now, and I’ve found the forge executable, but when I point AMD to it, it returns an error that permissions don’t allow it to be opened by the AMD software.

What do?
