Solved: “Google Chrome extension is blocked by the administrator”

When you try to install a Chrome extension, you may come across this error message:

LINER – Web/PDF Highlighter (extension ID “bmhcbmnbenmcecpmpepghooflbehcack”) is blocked by the administrator.

It is because your computer’s administrator user (mostly like the IT department if it is your work computer) blocked installing certain Chrome extensions through group policies.


If you have admin rights in your computer, follow the steps below to lift this restriction:

  1. Close Chrome
  2. Search for “regedit” in Start menu
  3. Right click on regedit.exe and click “Run as administrator”
  4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google
  5. Remove the entire “Chrome” container
  6. Open Chrome and try to install the extension

Another alternative is uninstalling and reinstalling Chrome but I don’t recommend it as it takes more time.

Note: Restrictions will be applied back once you restart your computer. However, you can keep using the extensions you have already installed.

Spread the word!

    1. Great observation. If you have Chrome open, you should restart it before trying. Another observation is that I was blocked from deleting the entire Chrome folder, it was simply enough to delete as much as I could from it’s content keys.

        1. Just in case, please back up your registry first
          Then make sure you open Registry Editor as Administrator
          If it doesn’t work, try to remove a key or sub-container first

    1. Asssuming that you are using Windows… Click Start menu on the bottom left corner of screen. Search for “regedit”. Click the first result
