Эта программа заблокирована так как не удается проверить ее издателя windows 10

When you try to install a new application, Windows verifies the file certificate to validate its authenticity. If the application is considered unsafe, it will block the installation and show you the «this publisher has been blocked from running software on your machine» error.

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

1. Unblock the Application Using File Properties

If the publisher is not listed in the untrusted list, you can try to force install the application using Command Prompt. To install apps using cmd, you need to execute the file path of the setup file with administrative privilege. This is one of the many useful things you can do using Command Prompt.

To install the app using Command Prompt:

1. First, you need to find the file path. That is the directory where the installer (setup file) is located. So, open File Explorer (by using Win + E) and navigate to the folder where your setup file is located.

5. Hit Enter to run the executable.
6. Wait for the installation wizard to appear and follow on-screen instructions to install the app without the error.

4. Disable SmartScreen Filter Temporarily

SmartScreen Filter is part of Microsoft Windows’s security solution. When enabled, it protects you against harmful websites and applications.

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

The steps below are for Windows 11; if you use Windows 10 or an older version, the steps may vary a little.

To disable SmartScreen Filter in Windows 11:

1. Press Win + I to open Settings.
2. Open the Privacy & Security tab in the left pane.
