How does one re-install them if the Store app doesn't work?
I have the exact same problem. I don't have any little pictures on my tiles, but when I click on a tile (that isn't also on my desktop), the tiles just go to a blank screen. For me this screen is green because my background is green.
I was reading that everyone said "trying uninstalling the tiles" but my app store tile also didn't work, so I tried something off a limb.
Go to the top right corner of your screen and slide it downwards, to have the menu appear. Then, click on search, and type in an app that you do not currently have on your computer. It will search for it through the app store app, which kinda activated
mine.
From there, i started unstalling and re-installing apps.
On the other note, i myself still need some assistance. Everyone is talking about Avast having this problem but i don't have avast, and that's not the only category of people experiencing this. On some of the apps that i tried to redownload, i get "Error
0x80070002" and some apps start to fail the download. I currently can't re-install NETFLIX due to this error. If anyone knows what this error is and/or knows how to fix it, i would appreciate it greatly.
