When attempting to run an application 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 – Run from Command Prompt
- Right-click the program icon, then choose “Copy as path“.
- Hold down the Windows Key, then press “X“.
- Choose “Command Prompt (Admin).
- From the Command Prompt, right-click and paste the target of the application into the Command Prompt box, 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 – Remove Publisher from Untrusted List
- Open Internet Explorer.
- Select “Tools” > “Internet Options” > “Content” > “Publishers“.
- In the “Certificates” window, select the “Untrusted Publishers” tab.
- If the software publisher for the software you are trying to run is listed, remove it.
Fix 3 – Unblock the File
- Right-click the icon to the program, then choose “Properties“.
- Uncheck the “Block” box, then select “OK“.

Thank you so much, tried all on different times and all worked. Recommend the first one especially.

Just realized the other method I posted is actually Fix 3 in the article. Didn’t continue reading after fix 1 worked :D

One of my applications won’t run. When the shortcut is double-clicked, it loads for a while but then nothing happens.
Fix 1 worked like a charm. Thank you.
Another way I figured out works for me is:
1. right click.
2. In the “General” tab you can see a message saying something like “this application is from another computer and is blocked for security purpose”
3. click the unblock button .
4. Can now be ran through double-clicking.

I’m tired of googling for today, as I don’t remember where I may have set this previously, but do you happen too know where this is in group policy? I remember setting it for a problem employee but now it’s causing an issue with an update file and I’m not sure where it is when I had 5 mins to look earlier.

Wow even when the remove button in Fix 2 is greyed out, Fix 1 still works?!?! That’s weird but thx
