Clean Vista (v6.0.6000) install
Clean CMUD 1.17 install

When you close CMUD you get a message saying
"This program requires a missing Windows component"
...
"This program requires D3DRM.dll, which is no longer included in this version of Windows."

Google shows D3DRM.dll to be part of DirectX 9
Vista ships with DirectX 10

Doesn't seem to be causing much of a problem (though only installed and opened CMUD for 30 seconds or so)

Getting it here as well.

Anyone have any idea what D3DRM.dll is used for? And if they removed it in DirectX 9 then what is it replaced with in DirectX 10? I find it very wierd that you get the error message when *exiting* CMUD rather than when starting it. Makes me wonder if this is actually still a bug in Vista.

It looks like it's been deprecated in DirectX 10. As per this link (http://msdn.microsoft.com/library/en-us/dnlong/html/AppComp.asp?frame=true#appcomp_topic14)

It's for Direct 3D Retained Mode... whatever that is. My only 3d graphics programming was in OpenGL. But anywhere here's a link that could shed some light. http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnardir3d/html/d3dapi.asp

I thought Vista was supposed to come with DirectX10 support and DX9 backwards compatibility?

Anyhow.. according to this, retained mode hasn't been updated since DirectX3.. so that would be long since deprecated

Hmm, not sure I'm going to be happy with Vista if it doesn't support DX9 properly...I have a *lot* of games. Hopefully they will improve this when people complain about it.

Anyway, I'll see if I can find where that DLL is referenced in CMUD. I'm using 3rd party DirectX components (DelphiX) and I have the source code, so I should be able to find the reference to that DLL and remove it in a future version.

I still think it's wierd that it gives the error on exit instead of on startup.

Did you try installing DX9 from the microsoft site? Vista doesn't come with DX9, but you can download and install it. I have a lot of money invested in games too :).

I'd expect if you try and install DX9 then it'll tell you that you already have DX10. I wouldn't worry about it though, as much as people like to slate MS, they're far too savvy to remove games compatibility when they're hawking a new OS. By the sound of it this dll is something hungover from DX3, and it doesn't actually stop CMUD working either.

Actually DX9 will install correctly, I run a number of my games in Vista with DX9... Oblivion, M2TW and Caesar 4 being the latest.

The reason why this works is that DX10 uses a completely different architecture and provides no backwards compatibility like older versions did, so it allows side by side install with DX9 for compat.
