How to fix “This editor has been blocked from running” error in Windows 10 and 11

If Windows is preventing a legitimate app from installing, there are ways to get it onto your system anyway.

When you try to install a new application, Windows checks the file’s certificate to validate its authenticity. If the application is deemed insecure, it will block the installation and display the error “this publisher has been blocked from running the software on your machine”.

Another reason for this error is that your system administrator is blocking the installation of certain applications on your PC. Whatever the reason, if you know the app is genuine, here we show you how to unblock and install blocked apps in Windows.

1. Unblock the app using file properties

You can modify the security attributes of executables using the File Properties tool. Windows can detect dangerous files from another computer as a threat and block them to protect the user from malicious threats.

You can manually unblock these files using file properties. Here’s how.

  1. Right-click on the blocked installer file and select Properties.
  2. In the Properties dialog box, open the General tongue.
  3. Then click on the Unlock button under the Security section.
  4. Click on Apply and OKAY to save changes.

If Windows keeps reporting downloaded files as a threat, here’s how you can stop Windows from blocking your downloaded files. If there isn’t Unlock in the file properties, go to the next step.


2. Manage and unlock editor

You can remove your application publisher from the list of untrusted certificates to facilitate the installation of the blocked file. You can do this by using the Internet Properties dialog through the Control Panel. Here’s how.

To remove the publisher from the list of untrusted certificates:

  1. Hurry Win + R open To run.
  2. Type control and click OKAY open Control Panel.

  6. Then click on the Certificates button under the Certificate section.
  7. In the Certificate dialog box, click the little right arrow button (top right) until you see the Untrusted publishers tongue.
  8. Here you will see a list of blocked publishers. Go through the list and locate the editor you want to unlock. Explore it Familiar name column to find the publisher’s name.
  9. If found, select the editor you want to remove and click on the Remove button.
  10. Click on Yes to confirm the action.
  11. Then click on close then click Apply to save changes.

Now try to run the installer and check if the error “this publisher has been blocked from running software on your machine” is resolved.

3. Install the app using Command Prompt

If the publisher is not listed in the untrusted list, you can try to force install the app using the command prompt. To install applications using cmd, you need to run the installation file path with administrative privileges. This is one of the many useful things you can do using the command prompt.

To install the application using the command prompt:

  1. First, you need to find the file path. This is the directory where the installer (setup file) is located. So, open File Explorer (using Win + E) and navigate to the folder where your installation file is located.
  2. Next, right click on the file and select Copy as path. This will copy the file path to your clipboard.
  3. Then press the To win type of key orderedand click on Execute as administrator for Command Prompt.
  4. In the command prompt window, press Ctrl+V to paste the file path.
  5. Hit Walk in to run the executable.
  6. Wait for the installation wizard to appear and follow the on-screen instructions to install the application without errors.

4. Temporarily Disable SmartScreen Filter

SmartScreen Filter is part of the Microsoft Windows security solution. When enabled, it protects you from harmful websites and apps.

However, sometimes it can also block genuine apps after incorrectly identifying them as malicious. If you trust the publisher and the app, you can temporarily disable the SmartScreen Filter to complete the installation.

The steps below are for Windows 11; if you are using Windows 10 or earlier, the steps may vary slightly.

To disable SmartScreen Filter in Windows 11:

  1. Hurry Win + I open Settings.
  2. Open the Privacy and Security tab in the left pane.
  3. Click on Windows security.
  4. Then click on Open Windows Security.
  5. Open the Application and browser control tab in the left pane.
  6. Click on Reputation-based protection settings under the Reputation-based protection section.
  7. Flip the switch to Check apps and files to disable the SmartScreen filter for installing offline apps. Click on Yes to confirm the action.
  8. Then flip the switch to Potentially undesirable application blocking to turn it off. Click on Yes to confirm the action.

You can now run the installer and complete the installation. Once done, make sure to enable SmartScreen Filter in Windows Security.

Bypass Publisher Blocking Restriction in Windows

Windows uses several layers of security to protect your computer from malicious applications. However, these protective measures can also lead to false positives and prevent you from installing a genuine app.

Fortunately, you can modify the file properties or temporarily disable the SmartScreen Filter to bypass these restrictions and complete the installation successfully.
