This article will show you how to fix "An administrator has blocked you from running this app" error while loading snap-ins in Windows 10.

Recently, we came around a strange issue that prevents us to open built-in snap-ins in Windows 10. The system on which we faced the issue has only single account and that was the administrator account. But still, system seems to be not recognizing that account level and keep throwing following error while opening snap-ins:

This app has been blocked for your protection.

An administrator has blocked you from running this app. For more information, contact the administrator.

If you’re facing this issue, there might be few reasons for it:

  • You lost the administrative rights
  • The snap-in might be blocked by Windows SmartScreen
  • A Group Policy setting is imposing a restriction on snap-in
  • Admin approval mode is enabled in UAC settings

In case if you’ve lost admin rights, you may not be able to open things which requires UAC permissions such as Registry Editor. So if you can’t select Yes or No for UAC permissions, you’ve lost admin rights. This problem can be fixed by following steps mentioned here.

For other causes, you may try fixes accordingly.

FIX: An Administrator Has Blocked You From Running This App In Windows 10

FIX 1 – Via Windows SmartScreen Settings

Sometimes Windows SmartScreen settings might block the snap-ins and thus they fails to load. So can try turning off Windows SmartScreen for a while and see if you could open the snap-in then. Simply select Don’t do anything (Turn off Windows SmartScreen) option.
