Can't download, error code 0x80070015 every time

I installed the anniversary windows update. Got the 2nd smaller update that came out today too. I’ve downloaded the Halo app, and when I click download Halo 5 Forge in the Halo app, it brings me to the Microsoft store, I hit download, then says

"Try that again

Something went wrong

The error code is 0x80070015, in case you need it."

How do I fix this and download Halo 5? My computer meets recommended specs, and I have enough space available to download the game.
