where to find DirectX 11 registry keys?

Question

where to find DirectX 11 registry keys?

Anonymous

i am creating an installer and need to determine if a newer version of DirectX needs to be installed.

Going to (HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> DirectX ). and i see "Version"="4.09.00.0904" which i believe is the key for DirectX 9.0c But the thing is I already get DirectX 11 installed so where should i go to find the registry key for DirectX 11?

Thanks

The registry key location is same for DirectX 11 also i.e. HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> DirectX and it has the same version i.e. "Version"="4.09.00.0904"

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX]

"InstalledVersion"=hex:00,00,00,09,00,00,00,00

"Version"="4.09.00.0904"

So how do I detect if there is installed DirectX 9.0c also !?

Answer 2

hi thanks for the reply. i believe "Version"="4.09.00.0904" means version 9.0c

In this case then how do i know whether i really installed DirectX 9.0c or DirectX 11 by looking at registry? I know i can find this out by using dxdiag but i want to do it from registry. is this possible?

Thanks
