How To Fix Error: An administrator has blocked you from running this app

Have you ever encountered a frustrating message stating, “Administrator has blocked you from running this app”? It’s a commonly experienced issue, particularly on Windows operating systems, that can halt your efforts to launch a program or application. This message appears when the system’s security settings or certain policies prevent an application from running. While it might seem daunting at first, there are ways to navigate and potentially resolve this obstacle.

Why Show this Message

The message typically occurs due to security measures that Windows employs to safeguard the system from potential threats. These safety protocols often identify certain apps or programs as potentially harmful, triggering the block.

Potential Causes

Several reasons might lead to this message:

  1. User Account Control (UAC): UAC settings on Windows can restrict applications from running if they’re not recognized or authorized. This feature aims to prevent unauthorized changes to the system.
  2. Group Policy Settings: In organizations or networks, administrators might enforce policies that restrict certain applications for security or productivity reasons.
  3. Windows SmartScreen: Windows Defender SmartScreen might mark an application as unrecognized or potentially unsafe, thereby preventing its execution.

Resolving the Issue

Resolving the “Administrator has blocked you from running this app” message involves navigating through system settings and security measures. Here’s a step-by-step guide to potentially fix this issue:

1. Run as Administrator

Try running the application as an administrator:

  • Right-click on the application’s executable file.
  • Select “Run as Administrator” from the context menu.
  • This might bypass certain restrictions for that instance.

2. Adjust User Account Control (UAC) Settings

Windows User Account Control settings might be causing the block. To adjust these settings:

  • Go to Control Panel > User Accounts > Change User Account Control settings.
  • Lower the settings temporarily. Be cautious, as it may reduce system security.
  • Apply the changes and try running the app again.

3. Contact the Administrator

If you’re on a shared network or using a work computer, contact the system administrator:

  • They might be able to provide access or make necessary changes to enable the application.

4. Check Group Policy Settings

In organizational settings, administrators may enforce policies that restrict applications for security or productivity reasons:

  • If you suspect this is the issue, contacting the administrator or IT support is crucial.

5. Review Antivirus/Security Software Settings

Sometimes, security software might block an application by mistake. To address this:

  • Open your antivirus or Windows Defender settings.
  • Look for blocked applications or settings that could be preventing the app from running.
  • Add the application to the whitelist or mark it as safe.

6. App Compatibility

Ensure the application is compatible with your version of Windows:

  • Some older applications might face compatibility issues. Check for updates or patches to make it compatible.

7. Install or Run in Safe Mode

Try installing or running the application in Safe Mode:

  • Safe Mode starts Windows with only essential services, which might help bypass certain blocks.
  • Install the application or try running it while in Safe Mode.

8. Verify Source and Reliability

Be cautious about the origin and reliability of the application:

  • Download software from trusted sources to avoid potential security risks.


Encountering the “Administrator has blocked you from running this app” message can be frustrating, but it primarily exists to safeguard your system. However, it’s crucial to remain cautious when making changes to security settings, especially if you’re unsure about the source or reliability of the application in question.

Remember, reaching out for technical support or seeking guidance from system administrators, particularly in organizational settings, can provide insight and potential solutions to this issue. Sometimes, certain applications might need approval or installation by an administrator to function correctly.

By understanding the potential causes and implementing the suggested solutions, you can often navigate through this obstacle and resume using your desired applications without this blockade.
