DirectX 10 is the newest standard.
There is no need to download DirectX for Vista. it already bundles the latest version of DirectX.
DirectX 8.1 is old and unsupported. You would be better served by upgrading your directX.
DirectX is not about your operating system but it's about video card you have. Video cards available today support DirectX 11 and as far as you have drivers for such video card your will support DirectX. Make sure that you update DirectX.
DirectX 9.0c is not available for Windows 7; to actually install DirectX 9.0c, you would have to downgrade to Windows XP (any edition). In order to play games which require DirectX 9.0c without downgrading your installation of Windows, you must upgrade to DirectX 10.1 or later. DirectX 10.0 (initially included in Windows 7) did not include support for DirectX 9.0c, a decision that Microsoft ultimately repealed when DirectX 10.1 was released.
Since the release of DirectX 8.0 graphics cards have used programs/instructions known as Shader Models to help interpret instructions on how to render graphics sent from the CPU to the graphic card. Many games are increasingly listing Shader Model versions in their system requirements.However these shader versions are tied to the version of DirectX that you have installed on your PC which is then in turn tied to your graphics card. This can make it difficult to determine if your system can handle a certain shader model or not.To determine the version of DirectX you have running:1. Click on the Start menu, then "Run".2. In the "Run" box type "dxdiag" (without the quotes) and click "Ok". This will open up the DirectX Diagnostic Tool.3. In the System tab, listed under the "System Information" heading you should see a "DirectX Version" listed.4. Match your DirectX version with the Shader version listed below.Once you've determined the version of DirectX running on your PC you can use the below chart to determine what Shader Model version is supported.Please note DirectX versions prior to DirectX 8.0 do not support shader models• DirectX 8.0 - Shader Model 1.0 & 1.1• DirectX 8.0a - Shader Model 1.3• DirectX 8.1 - Shader Model 1.4• DirectX 9.0 - Shader Model 2.0• DirectX 9.0a - Shader Model 2.0a• DirectX 9.0b - Shader Model 2.0b• DirectX 9.0c - Shader Model 3.0• DirectX 10.0* - Shader Model 4.0• DirectX 10.1* - Shader Model 4.1• DirectX 11.0* - Shader Model 5.0*DirectX 10.0 and higher will not run in Windows XPOne recommendation prior to installing a newer version of DirectX is to ensure that your graphics card supports that version of DirectX.

SMOCK is a scaleable way of managing cryptographic keys.
Start->Control Panel->Administrative Tools->Services, locate the service which is called Cryptographic Services. If it was stooped start it pressing on the Start. By default the cryptographic service is on.
There is no need to download DirectX 3. Versions of DirectX up to DirectX 9 are backwards-compatible. So if you have one version, you can use games and programs that require a previous version. Besides, the DirectX 3 installerwasmeant to be used only on Windows 95, and would probably cause problems if installed on later versions.
just download the program called KMDXC(Just Google it). After downloading select directx 10 and click patch.
yes, directX 10 should be fine
