DirectX fail of the day

LloydA111

On my W7 machine I ran dxdiag, it reports that I'm running DirectX 11, but when I run OpenGL Extension Viewer it claims that I'm on DirectX 9.0C. I need to run a program that needs at least DirectX 9.0C. So I thought, well either way, I must have at least DirectX 9, but as soon as I run the program that requires it, it fails with "You must have at least DirectX 9.0C to run this." :doh:

The problem is you probably need a specific version (e.g. 9.0C 1.23.whatsit.1.5.june.2011.etc). I have about a million different versions of DirectX on my gaming rig as a result.

Really? Wow, now that is a failure to build in any kind of backwards compatability!

I had a similar issue with EverQuest and Windows Vista/7. Neither machine had DX9 on it, both had DX10. EQ wanted DX9. I was able to work around this because EQ told me the file name it couldn't find. I found the file and put it in the EQ folder and everything worked great. Not sure if Sony has fixed this or not, but apparently DirectX is not backward compatible.

It's not really meant to be. IIRC, there was a huge architecture change between DX9 and DX10 (not so much between DX10 and DX11 though).
