Windows 10Group Policy

Fix – This app has been blocked for your protection

On my Windows 10 machine, I installed G.SKILL software and when I launched it, the application was blocked. I received the error This app has been blocked for your protection.

Just below that message, I saw An administrator has blocked you from running this app. For more information contact the administrator. This message was confusing because my user account was member of built-in administrators group.

So I assumed that this app launches fine when you run it as administrator. It seems like I was wrong, I got the same User Account Control box with same message. At this point turning off the UAC also didn’t fix my issue. I had no issues with other apps however this was the only application that I wasn’t able to use.

First of all let me show you the screenshot. Here is what I got when I launched the Gskill.exe for the first time. There is no other option that you see except Close.

If you are experiencing same error – This app has been blocked for your protection, let me show you how to fix this.

Fix This app has been blocked for your protection

If your app is blocked with above error when you launch it, try the below steps.

  • On your Windows 10 computer click Start > gpedit.msc. This opens Local Group Policy Editor.
  • Navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options.
  • In the right pane look for policy setting – User Account Control: Run all administrators in Admin Approval Mode. Either right click the setting and click Properties or just double-click the policy.

This policy setting controls the behavior of all User Account Control (UAC) policy settings for the computer. If you change this policy setting, you must restart your computer.

You see two options.

  • Enabled: Enables Admin Approval Mode and all related UAC policy settings.
  • Disabled: Disables Admin Approval Mode and all related UAC policy settings.

Change the security setting to Disabled. Click OK.

You should immediately see a notification to restart the computer. Since we have modified UAC policy, you must restart your computer.

After the restart I could launch the application without any issues. I hope the steps mentioned this post helps you fix this issue. Let me know in the comments section.

  1. Thank you very much for the fix!!!!
    I have gone through many attempts and made many strange changes with no luck at fixing this aggravating problem. your fix worked perfectly. Very much appreciated.

  2. Hello Prajwal,
    Thank you for your post, would there be any reason why only 1 application is experiencing this UAC blocking? Mine starts happening when I revert back to the previous version of the app, after developer release a faulty update.

  3. This worked for Alienware AlienFX Editor. Previous solution was to open the exe from a command prompt, so it’s not like it was “secure” in the first place. Just annoying. Thank you.

  4. Fantastic. Thank you. Getting this error when trying to open software included with my mobo (Asus Aura), and running as admin every damn time is unacceptable. This nipped it in the bud!

    1. AGREE! This isn’t fixing anything. This is IGNORING it, which is NOT SECURE and btw cannot be done in our corporate environment because we intentionally force that policy. Now what do we need? I suspect it’s more related to the Publisher:Unknown and something potentially forcing something to be signed with a cert.
