This App has been blocked by your system administrator

On one of my 3 Windows 11 systems, I continue to be unable to run any of the Microsoft Store apps such as notepad, scan, calc, etc., including the Store app itself and instead get the following message - "This App has been blocked by your system administrator". I've spent many hours and visited many websites in an attempt to diagnose and resolve this problem - with no luck ! I've tried many suggestions posted on various websites with no positive results. I've uninstalled all of the Microsoft Store Apps and reinstalled them and still get the same message. Is there a comprehensive list of flags, settings (registry, for example), file properties, security policies, etc. listed anywhere that, if set, would cause this message to be issued, resulting in failure to start any of the aforementioned Store apps. I want to avoid reinstalling Windows from scratch - some not-so-obvious setting/policy is not allowing these apps from running. BTW, I am running Windows 11 21H2 (OS Build 22000.739). Any help would be appreciated. One last idea - are there any tracing capabilities that would log/trace the path from clicking on the app through to the point of failure ?

 

MRT blocked by system administrator?

Hello MeesterJake

please follow these methods

Method 1

check the setting of Applocker in GPO.

The path of the Applocker is Computer Configuration\Policies\Windows Settings\Security Settings\Application Control Policies.

Method 2

-Activate hidden administrator account

If you have an administrator account you can just switch to it and install the application, but if you don’t have the administrator account you can activate the hidden administrator account and use it install the application.

To active hidden administrator account do the following:

Start Command Prompt as administrator. You can do so by following Step 1 from the previous solution.

When Command Prompt starts, type the following and press Enter to run it:

net user administrator /active:yes

An administrator has blocked you from running this app Windows 10

Sign out of your current account.

You should see new Administrator account available. Log in to it.

Locate the application you want to install and run it.

You should be able to install it without any problems.

After you’re done, switch back to your regular account.

If you want to disable administrator account, run Command Prompt like in Step 1, and type the following:

net user administrator /active:no

If the issue persist

Method 3

sometimes your antivirus software can enforce certain policies that can prevent you from installing or running certain applications. To fix that, you need to check your antivirus settings and see if the antivirus is blocking the application.

If you can’t find these options, you might want to try disabling your antivirus

Method 4

-Disable Windows SmartScreen

Sign in to the administrator account. If you don’t have administrator account enable one like we explained in the previous solution.

Open the Settings app.

Navigate to Update & security section.

Your administrator has blocked this application because it potentially poses a security risk

Select Windows Defender from the menu on the left. In the right pane, click Open Windows Defender Security Center button.

An administrator has blocked you from running this app Windows 10

Now click on App & browser control.

Your administrator has blocked this application because it potentially poses a security risk

Set all options to Off. To turn off SmartScreen feature, you need to set Check apps and files, SmartScreen for Microsoft Edge, and SmartScreen for Windows Store apps to Off.

Method 5

-Make changes to the group policy

If you’re getting Your Administrator Has Blocked This Program error message, the problem might be caused by your Group Policy settings. However, you can easily fix that by making a few changes. To do that, just follow these steps:

Press Windows Key + R and enter gpedit.msc. Press Enter or click OK. This will start Group Policy Editor on your PC. Keep in mind that this feature isn’t available on Home versions of Windows, but you can enable Group Policy Editor in Home version of Windows
10 with a few tricks.

Your system administrator has blocked this program GPO

When Group Policy Editor opens, navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options in the left pane. In the right pane, double click on User Account Control: Run all administrators in Admin Approval
Mode.

Your system administrator has blocked this program Avast

When the Properties window opens, select Disabled and click on Apply and OK to save changes.

Your administrator has blocked this application because it potentially poses a security risk

If you can’t access Group Policy Editor, you can also make these changes from Registry Editor by doing the following:

Press Windows Key + R and enter regedit. Press Enter or click OK to start Registry Editor.

An administrator has blocked you from running this app Windows 10

When Registry Editor opens, in the left pane navigate to ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem key. In the right pane, double click on EnableLUA DWORD.

Your system administrator has blocked this program Regedit

Change the Value data to 0 and click OK to save changes.

Your system administrator has blocked this program AVG

After doing that, restart your PC

I hope it helps you

 

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.
