Many people get such problem after udgrading to Windows 8.1. When you try to launch the Windows store app, it just stuck at there and the little loading cicle keeps going around and then takes back to start screen. The screen resolution has been setted up as 1366X768.
I also faced the same issues on my tablet and computer. I uninstalled avast antivirus but nothing happened. Then used Event Viewer and find these information:
“Activation of app winstore_cw5n1h2txyewy!Windows.Store failed with error: The remote procedure call failed. See the Microsoft-Windows-TWinUI/Operational log for additional information.”
If the store app will no longer open in Windows 8.1, you could try the following tips to resolve the problem.
* You need to re-register the Store app.
* Press the Win + X keys together, or right-click on the Start button. And select “Command Prompt (Admin)” from the pop-up menu.
* Within the Command Prompt Window, input the command and press Enter to run it:
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
Once the process have been done, go to check if it is OK. Works fine on my Surface Pro tablet.
