Fixed: This application was blocked by your system administrator

The Windows 10 operating system is aggressive when it comes to protecting users from suspicious or potentially malicious software. It’s generally beneficial, but it can also prevent users from installing software that they think is safe. As a result, an error message appears: “The administrator has not allowed you to run this application” or “This application is blocked for your protection.”

The Windows error (more like a notification) prevents users from downloading and/or installing applications. In previous versions of Windows, this error message was generated only by installed anti-virus software, but today Windows includes built-in Windows Defender and UAC (User Account Control), which is responsible for protecting users from potential threats. The “Administrator has blocked this application from running” error message means that the system does not allow you to run a suspicious installation file (setup.exe), which could infect your computer with malware or other viruses. If you are not sure if an installation file is trustworthy, we recommend that you do not ignore this warning.

This message may also appear when you try to download or install legitimate software, such as hardware drivers. In this case, it can be frustrating and limit your actions. Fortunately, there are ways to avoid this warning. Read the following guide and try the suggested solutions.

To fix the "This application is blocked by your system administrator" error

Disable Windows SmartScreen

Windows 10 has SmartScreen, a cloud-based component that helps protect against phishing and malware attacks. It compares downloaded files to a list of programs and software websites that have been flagged as dangerous.

You will also be alerted if the file you are trying to run is not trusted and popular among Windows users. To disable this feature and see if it’s causing the problem you’re experiencing, here’s what you need to do:

  1. Press the Windows logo key to open the Start menu.
  2. Type “Smartscreen” in the search bar and click on “App and Browser Controls” in the results.
  3. In the Windows Defender Security Center that opens, go to “Check applications and files” and select “Disabled”.
  4. Now try running your file again. See if the problem is bypassed.

To avoid exposing your computer to malicious elements, remember to re-enable Windows SmartScreen after successfully running your file. Just follow the instructions above, but in step 3, choose “Warn” or “Block” instead of “Disable”.

If you don’t want to disable SmartScreen, there is another option:

  1. Right-click on the file you want to run and click “Properties” on the context menu.
  2. Under the General tab, uncheck the Unblock checkbox.
  3. Click Apply -> OK. The file will then be recognized as safe and bypass SmartScreen. Then you can try running it again.
Run the file from the command line

You can bypass the error message by using the advanced command line to run your installation file. Just follow these simple steps:

  1. Right-click on the file you want to install and choose Properties from the context menu.
  2. On the General tab, highlight and copy the entry under Location. For example: “C: Users downloads”.
  3. Now press the Windows + X logo key and select “Command Prompt (Admin)” from the menu.
  4. Paste the location of the file you copied in step 3 into the Advanced Command Prompt window.
  5. Minimize the advanced prompt and return to the File Properties window (as shown in step 1). Copy the file name (This is the entry in the box at the top of the page. It has the .exe extension at the end. For example: “we set up all.exe”).
  6. Maximize the enlarged command line. Type “, then paste the entry you copied in step 5. You now have the location and name of the file. It should look like this: “C: Users isDownloadswlsetup-all.exe”.
  7. Press the Enter key on your keyboard to execute the command.

Check to see if an error message appears.

Installing an application using a hidden administrator account

If you use a hidden administrator account, you may be able to successfully install your application. Here’s how to do it:

1.) Press the Windows logo key to open the Start menu, then type “command prompt” in the search box.
2.) Right-click on the option in the list of results and click “Run as administrator.”
3.) Copy and paste the following command into the Advanced Command Interpretation window and press Enter to execute:

network administrator /active: yes

You should then see a “Command executed successfully” confirmation.

4.) Log out of your current user account. To do this, simply click on the Windows icon in the lower-left corner of the screen. Now click on the user logo and select “Logout”.
5.) Now log in under your administrator account.
6.) Try to install the file you are having trouble with.

If you want to disable the hidden administrator account after successfully running the file, open the extended command line. Copy and paste the following entry into the window, then press Enter:

user network administrator /active:no

Temporarily disable your antivirus program

On your computer, a third-party antivirus program may display the message “The administrator has blocked this application from running”. So the first thing to do is to add an exception to the application you are trying to run. To find this setting, we recommend that you consult your antivirus program’s user manual or just search for it online.

You also have the option to disable the antivirus software completely if you cannot find a way to add an exception for the problematic application. However, don’t forget that you should always have a reliable security program active on your PC to protect against possible threats.
