"This app has been blocked by your system administrator" error when you to start Windows Store apps


When you try to start a Windows Store app in Windows 8 or in Windows Server 2012, the operation fails. Additionally, you receive the following error message:
This app has been blocked by your system administrator.

error msg


This issue occurs because an administrator has deployed an application control policy (AppLocker) on the computer. By design, all Windows Store apps are blocked if an AppLocker policy is applied.


To allow the Windows Store app to run, a domain administrator can use AppLocker to edit application control policies by using one of the following methods (whichever is most appropriate to their situation):
  1. Create a default rule that allows all Windows Store apps.
  2. Create rules that allow individual Windows Store apps.
Note The rules must be edited from a Windows Server 2012-based domain controller or from a Windows 8-based computer that has the Remote Server Administration Tools installed.
