When attempting to run software on your Microsoft Windows 10 computer, you may encounter an error that says “This publisher has been blocked from running software on your machine“.
This message may appear because a systems administrator at your organization has blocked the publisher. It may have also happened by accident when the software was previously installed.
Whatever the reason, you can usually fix this error with these steps.
Fix 1
- Select the “Start” button, then type “CMD“.
- “Command Prompt” should appear as an option. Right-click it, then choose “Run as Administrator“.
- From the Command Prompt, type the target of the application, then press “Enter“. If you don’t know the target, you can usually obtain it from the icon of the application by right-clicking and selecting “Properties“. The path and name will be shown in the “Target” field.
The program should open without error.
Fix 2
- Right-click the Start button and choose “Control Panel“.
- Select “Network and Internet” > “Internet Options” > “Content” > “Certificates“.
- Scroll the tabs over to the right and select “Untrusted Publishers“.
- Select the publisher of the software you are trying to run, then select “Remove“.

Tetsuji says
I tried fix1 and it succeeded. However, I want fix2.
I can see my targets (Avast, AVG, Malwarebytes) in untrusted publishers, but remove button cannot be activated. How can I do it?
Glenn says
The target is like this “C:\Users\Glenn\Desktop\Antivirus_Free_Edition.exe”
michael says
the target of the application is the name and path to that application. so if you want to install a program named nemo , which is located in your download folder, what you do is – get into cmd as an administrator, go back to that program you are trying to install, right click on it, go to properties,copy and paste the whole path listed on the location into the cmd: usually starts with c. then look at that path and if the name of the program isnt showing, then copy the name of the program as is on the upper rectangle block above the location and paste directly after the first paste within cmd, with a back slash preceeding the first paste and click enter……
Kevin says
Fix 1 acts like its working then fails. Fix two, I have no untrusted publishers,
Saim says
What is the “target” of the application. I can’t find it anywhere in the properties.
Arjuna says
I am having this issue installing trusted Samsung drivers. The first step didn’t work for me (literally nothing happens when I try to execute the file). The second step- I do not see anything under untrusted publishers. Yet it still still blocks me from running the file. I am the system admin and have all permissions.
