if game requires directX9 but i got direcX10 what i do?

[alluton]

so i got game(revolution under siege) and it needs directX9 to run. Installion worked just fine. I have tried to simply install directx9 to computer but it gives error message: An infernal system error occured. Please refer to DXError.log and DirectX.log in your windows folder to determine problem.  I treid to use windows search feature. I found DirectX.log but not DXerrro.log. Here is DirectX.log:http://pastebin.com/kTa4FtHf
As you may guess already im using windows vista. And service pack 1. Ask what else you need to know.

If you have DX10 then games that require 9 will work with 10 because it is a newer version...

You have DirectX9 installed as well. Most games requiring it will install it if it's not already present. DX9 on Vista and win7 is a side by side installation. DX9 and DX10/11 are completely incompatible with each other and use a new API.

read this Microsoft KB article regarding obtaining latest DirectX.

I guess you may have already tried, but maybe give the download that M'Soft's official KB page links to a try.

DirectX10 was not meant to be uninstalled, especially not the way you were doing it. Since Vista, DirectX is part of the OS, unlike 9.0c and previous versions. Click this link, download the installer, run it, and it should repair whatever damage you've done to Dx10.

If your games won't run under Dx10, download the Dx9.0c redistributable and install it. You should also be able to find the exact same installer on one of your game CDs, as they usually attempt to install it if it's required.

You said DirectX 9 failed. My first link was the installer for DirectX 10 and 11, since you've now deleted portions of that. DirectX 10 is part of Vista and you should repair it before trying to continue with installing Dx9c. That, or you can do it the hard way and reinstall your OS. Either way...
