I've been having the same issue and have tried every fix I've seen. Nothing has been working for it, and I cannot download any apps off the xbox app either. Whenever I start up my computer, it tells me that Microsoft Visual C++ 2015 UWP Desktop Runtime Package was installed, too. But then wants to try to install any time I try to install No Man's Sky. Just shows this and never makes any progress.
Also, every time I restart my computer, I get a notification that C++ installed successfully, but when I look at my notifications, this is what I see:
I also unistalled and reinstalled it, but Microsoft Store is still attempting to download it from the store every time I try to install No Man's Sky.
