DirectX 9 (and 10)

[BeautifulCoconut]

I downloaded the DirectX 9.0 setup exe from the Microsoft website. Whenever I try to load it, the license agreement comes up and I accept that, but as soon as the "Initializing" stage appears, there is an error that tells me to check the error logs. This is for DirectX 9.

The DXError.log states:

I have no idea what to do or what parts of the error log are important.
Any ideas?

I have Vista with a NVIDIA GeForce 8400M GS. Any other details needed?

Why would you want to install DX9? Vista have DX9 and DX10 built in. (Yes it apparently have both because DX10 isn't backwards compatible with earlier versions of DX).

[BeautifulCoconut]

I uninstalled Vista and reinstalled it, which started the problem. It's not located on the Drivers CD that came with the laptop either. I also cannot find it on my computer, so I do not believe it is installed.

I do not believe it is installed

Go Start, type in:
dxdiag.exe
Hit Enter.
It'll tell you.
