Hi all,
I'm trying to detect if certain pixel and vertex shaders are installed
on a machine. I have followed the exampled in the Wix 3.0 help, but I'm
not getting the desired error message.
<PropertyRef Id="WIX_DIRECTX_PIXELSHADERVERSION"/>
<PropertyRef Id="WIX_DIRECTX_VERTEXSHADERVERSION"/>
<CustomAction Id="CA_CheckPixelVertexShaderVersion" Error="[ProductName]
This application requires DirectX 9 with pixel shader and vertex shader
version 2.0 or greater, for Previewer to work correctly." />
<InstallExecuteSequence>
<!-- Things to do during install -->
<Custom Action="CA_CheckPixelVertexShaderVersion"
After="WixQueryDirectXCaps">
<![CDATA[(WIX_DIRECTX_PIXELSHADERVERSION < 200) AND
(WIX_DIRECTX_VERTEXSHADERVERSION < 200) ]]>
</Custom>
<!-- Things to do during uninstall -->
</InstallExecuteSequence>
<InstallUISequence>
<Custom Action="CA_CheckPixelVertexShaderVersion"
After="WixQueryDirectXCaps">
<![CDATA[(WIX_DIRECTX_PIXELSHADERVERSION < 200) AND
(WIX_DIRECTX_VERTEXSHADERVERSION < 200) ]]>
</Custom>
</InstallUISequence>
When I run the above code on a virtual machine, which obviously does not
have the required pixel shader support, the log files says...
Action 14:36:53: WixQueryDirectXCaps.
Action start 14:36:53: WixQueryDirectXCaps.
WixQueryDirectXCaps: Error 0x8876086a: GetDeviceCaps call failed
Action ended 14:36:54: WixQueryDirectXCaps. Return value 1.
But My error message is never displayed.
When I run it on a real machine I correctly get the
WIX_DIRECTX_PIXELSHADERVERSION and WIX_DIRECTX_VERTEXSHADERVERSION
variables set with the right values.
What am I missing/doing wrong?
