I'm pretty sure that installing DX9 on Vista doesn't override the DX10
files, it just adds a few extra ones that are required for certain DX9
games.
If you want to make sure, type 'DXDIAG' in the search bar of the start
menu and open the program that appears in the list.
The bottom entry of the intro page that appears show which DX** version
your pc has. I'd been very surprised if it doesn't show as DX10.
Just in case I'm wrong, or you want to make extra sure, you can download
the latest version of DX10 here....
