Sometimes we want to remove an app we installed on our windows 10 PC for testing for testing but instead of a simple click and wait scenario we get this error.

This app has been blocked for your protection. 

An Administrator has blocked you from running this app.

For more info contact the administrator

C:\Windows\installer\bb7400b.msi
Publisher: unknown
File origin: hard drive on this computer
Program location: C:\windows\installer\bb7400.msi
I'd include a screenshot but I wasn't planning to write this note.

So you contact your administrator (yourself) and get yourself committed to a mental health facility. (LOL) Kidding aside, this is a bit frustrating but then again this happens often. Here's how to run the said app installer/uninstaller as an admin from the command prompt.

First step is to take note of the Program Location. Write it down if you have to.

  • Press Windows Key -> R (Run)
  • Type "cmd"
  • press "Ctrl-shift-Return"
  • press "alt-y"
Make sure that you have an Administrator Command Prompt

Check the program location you noted earlier if its extension is .exe you can just type the whole program location at the command prompt and press Enter.

If its extension is .msi use the following:

msiexec /uninstall C:\Windows\Installer\bb7400.msi

You should now be able to uninstall that unwanted app without your Administrator blocking you.
