For several days now I have had difficulty opening Firefox. It seems to be taking a long time to open. When it eventually responds I usually get a window headed: "Update failed". The window reads: "There were problems checking for, downloading or installing this update. Firefox could not be updated because: The Update could not be installed (patch apply failed). You can update Firefox manually by vistiing this link and downloading the latest version: http://www.firefox.com

The link takes me to a Firefox for Android page. I am working from a desktop.

I have tracked it down to a file called updater.exe (from memory) that is in a file called 0. When I delete this file it is quickly redownloaded and continues to cause a problem.

How can I get rid of it?

And does it have anything to do with the disappearance of my Norton toolbar?

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu) and confirm all upcoming messages.
  3. Now, uninstall Firefox by following the steps mentioned in the Uninstall Firefox article.

IMPORTANT: On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do not check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox user profile data will be removed from your computer.

After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:

  • (On 32-bit Windows) C:\Program Files\Mozilla Firefox
  • (On 64-bit Windows) C:\Program Files (x86)\Mozilla Firefox
  1. Go to the Windows Start menu and click on "Computer".
  2. In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
  3. Find the "Program Files (x86)" folder or "Program Files" folder.
    • On 32-bit Windows, double-click the Program Files folder to open it.
    • On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the Program Files (x86) folder.
  4. Look for a Mozilla Firefox folder. If you find one, right-click it and select Delete and confirm that you want to move the folder to the Recycle Bin.

Now, go ahead and reinstall Firefox:

  1. Double-click the downloaded installation file and go through the steps of the installation wizard.
  2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!

Thank you Tylerdowner, I've followed your instructions and it seems to have resolved some of the issues. I'm no longer getting the failed update.

This update to Firefox 18 seems to have caused a lot of problems. I still haven't got the Norton toolbar and the extensions page isn't uploading. I also had problems with email last night although they worked on IE and work on Firefox this morning.

Still getting "The Update could not be installed (patch apply failed)" after reloading Firefox

It helps to try to open 3-15 Firefox windows. Seems to speed up the failure to get the failed download window. Otherwise it will sit in limbo forever.

Interestingly, the download page thinks Firefox is up-to-date. I had 19.0, latest was 19.02.
