Computer Tip: MS12-034 fails with 0x8007F0F4 error code

Have you tried to install MS12-034 (2686509) and when installing this update, the update fails with the following error message:

Setup cannot continue because one or more prerequisites required to install KB2686509 failed (0x8007F0F4)

If you look at %windir%\FaultyKeyboard.log, it indicates that the keyboard layout is registered on the computer but the files aren’t located in the %windir%\System32 folder.

If %windir%\FaultyKeyboard.log is not created and you received this error, there are some other possible issues and solutions.  See

In my case, the update did fail. A while back I kept on hitting the Caps Lock key by mistake. So I modified the keyboard layout and disabled that key. As soon as I enabled the key, MS12-034 installed correctly.
