DX error

Hi,
I reinstalled Vista x64 and was trying to update the DX runtime. So I got the Nov. 2008 and it installed most of it, but it had some errors. Here is what it said from my log files:

--------------------

Error: (5) - Access is denied.

Is there anyway for me to fix these errors? I tried running the same update again after restarting, but it said that it seemed that my DX runtime was up to date.

Thanks for your help
