Have been trying to install this since yesterday, I've tried doing clean boot, deleting and re-downloading the update etc. Not sure what else to do, it tells me it's an important update so I need to get this sorted.

I had the same problem and found a solution.
For this update, TEMP file location should be set to default C:.
I changed Temp file location from RAM disk to C:\ for this update and it worked. Thereafter I changed the Temp file location back to RAM disk.
sorry but ive not got much computer knowledge im having the same proplem with the important update so can u tell me how to do the TEMP file thing that youve said as dont even know where to look i have tried but not sure what to do or look for plz help ty
Thank you for answer! I would like to clarify an answer.
My TEMP directory was NOT on RAM drive, it was in %userprofile% folder for user and in %windir% folder for system (by default after installing system).
I created folder c:\temp and assign value "c:\temp" to user and system variables TMP and TEMP.
After this KB2685811 was installed successfully.
Then i returned previous values of all variables.
I'm also having this problem.
But my TEMP is already in "%windir%\temp" which is in C:\
and still get the error.
Any help?
Thanks this worked! I sometimes forget I use a RAM disk. :)
