When you try to start a Microsoft 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.
This issue occurs because an administrator has deployed an application control policy (AppLocker) on the computer. By design, all Microsoft Store apps are blocked if an AppLocker policy is applied.
To allow the Microsoft 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):
- Create a default rule that allows all Microsoft Store apps.
- Create rules that allow individual Microsoft Store apps.
