"There is no direct way to obtain the DirectX version number. However, each
version has a characteristic set of objects and interfaces.
...
Rather than provide a detailed list here of each version's characteristic
interfaces and objects, you should refer to the DirectXsoftware development
kits (SDKs) sample section. One of the samples is a function, GetDXVersion,
that includes tests for all DirectX versions. GetDXVersion returns an integer
that corresponds to the DirectX version that is present on the system. As long
as this integer is greater than or equal to your desired version number, your
application will run normally. You can find the sample code under your SDK root
folder at \Samples\Multimedia\DXMisc\GetDXVer."

Subject: [WiX-users] Detecting the version of an installed file?
Howdy all,
I'm working on an installer that needs to detect whether a specific version of
DirectX 9.0 is installed (9.0c). Unfortunately a standard registry check using
this:
<Property Id="DIRECTXVERSION">
<RegistrySearch Id="DirectXVersion" Root="HKLM" Type="raw"
Key="SOFTWARE\Microsoft\DirectX" Name="Version"/>
</Property>
doesn't work since the Version value is the same for all flavours of DirectX
9.0. I do know a specific file that is installed in c:\windows\system32 that
identifies the version of DirectX installed, and also know what version number
I need to see on it to be happy.
How do I look up this file's version, so I can put that value into a property
and the use it as a condition? Alternatively, does anyone know of a better way
to detect the specific version of DirectX 9.0 that is installed on a machine?
Thanks!
Neil
