Windows 7: DirectX Web Installer failed?

Direct X web installer failed to install in windows 7 ultimate?
"An internal system error occurred. Please refer to DXError.log and DirectX.log in your windows folder to determine the problem." I can't find these in my windows folder

What was the reason of me trying to install the web installer well it was because i wanted to play my new game fallout3 and that came with a error " THE PROGRAM CAN'T START BECAUSE XINPUT1_3.DLL IS MISSING FROM YOUR COMPUTER. TRY REINSTALLING THE PROGRAM TO FIX THIS PROBLEM. and from doing some googling i have not found any solution just a bunch of contradictions.

I am hoping someone can help me out windows 7 has been a night mare for me

Try this version > Download details: DirectX End-User Runtimes (February 2010) < its the full verison that you can install locally.

alpha why not the June redistributable ?

Download details: DirectX End-User Runtimes (June 2010)

HeadsUp if it helps any it isn't you, the web installer has been buggy for a lot of people for a long time. It either works or it doesn't (I've had it work one update, and not the next over the years).

Ops, Google linked me to the FEB 2010 version and it looked new enough that I just assumed it was the latest. My bad.
