Microsoft Update wants to install the latest version of Silverlight (KB970363) on my computer but every time it goes i get the same error. (A picture of the error is attached).
I tried browsing to the folder, but it still did not work. I tryed uninstalling so i could just install off of Silverlight's site but the un-installation gives me the same window. I deleted silverlights file in program files and tried again, but still the same problem. What should i do ? I'm using Vista.

Thanks.

These windows updates drive me crazy :/
