I downloaded the 11GB launcher from the Microsoft store and upon attempting to open the launcher i am greeted with this error!

I have restarted the computer and also have unistalled and reinstalled the launcher. There is no "WindowsApps" folder to be found on my computer so I am at a loss as to what to do. Any help would be appreciated

Ok so i did some more research and have found the folder that the error describes. Turns out that WindowsApps is hidden and that you do not automatically have permissions for it. I gave myself permissions and cracked found the right folder and this is what it looks like inside.

Hopefully this will give more insight into what the problem could be.

I had this issue, found a github page saying to use repair function of windows store, as I did, took 3 hours to finish and gave me an error and removed the game itself.

Really good, I really love the way UWP applications behave.
