Today’s blog is going to cover some issues regarding the installation of MS12-034 (2686509). When installing this update you may encounter the following error message:
Setup cannot continue because one or more prerequisites required to install KB2686509 failed (0x8007F0F4)
The existence of %windir%\FaultyKeyboard.log indicates that we found a keyboard layout registered on the computer but the files do not exist in the %Windir%\System32 folder.
If you encounter the error and a FaultyKeyboard.log is not created there is some other possible causes and solutions. The following KB article is being updated on regular basis to list out possible solutions so you should always check it for updated information

Thanks and I hope this helps Scott McArthur Senior Support Escalation Engineer
It doesn't work and for the vast majority who lack the skills or knowledge to hack the registry any suggested fix for the end user to do this is absolutely NO fix. Besides for a great many even attempting and doing the suggested registry hacks find the patch still wont install.
It can and should be pulled until Microsoft actually can provide one that will install.
Afer 3+ weeks fighting this and no real solution I turned off auto-update and will remain only will download the malware removal tool manually.
I have about 9 still open support cases where the current status is "Subject:Case is under discussion with TM and TSL"
That KB is still confusing.
In cases where people remapped a key there IS NO faultykeyboard.log file.
Other failures include when people have upgraded from Windows 98/ME. I also am tracking an issue where people are on a Mac with Bootcamp and XP's updating is barfing.
Mine failed but it was because I had modified the keyboard layout [disabled the caps lock as I kept on hitting it by mistaked]. As soon as I reset the layout [with the utility], it installed fine.
Mine just fails, no 0x... message or anything. I have no idea where to start.
The recent fixit release isn't any help as it fail. The message has no error number, code, or status indicating why just some generic wording.
Same here. No error number - nothing. Just "failed".
Tried the installer - get prerequisites message. Don't have time for this!!
Glad we're looking at another OS!! (We're not doing Windows 8 - will encourage too many employees to play on gadgets rather than work.)
i need your help trying to install kb2686509 it says one onr more prequires then it tells me to go to c:\windows\kb2686509.log i dont understand email me back at email@example.com or firstname.lastname@example.org k thank you derek
Here is a more useful fix, tells you how to find and remove the corrupt registry entries.
Ran into this with a Window XP Pro configured as a Kiosk. We had modified the "[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout" key years ago to remove access to specific keys by the end-user.
