Hi,

You can detect the DirectX version by querying this key in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX\Vers ion

DirectX 8.0 stores 4.08.00.0400 as its version in the registry.

Hello:
Like doing the following thing:
If the version of Directx is greater to the 8, to execute a program.
If the version of Directx is smaller to the 8, to verify that Windows has and to install Directx 8 depending on the version of Windows. Later to execute a program.
Thank you very much.

Hi,

Basically you would follow these steps:

Read From Registry
Read the version into: %DirectXVer%

Execute Program
Execute DirectX installations
Boolean Condition: %DirectXVer% < 4.08.00.0400
Wait For Return: Checked

Execute Program
Launch your main program
