OK, I'm running Windows 7 7201 64-bit. I installed COD4 1.7 last night and when asked about installing DX9 I selected "No" since my Windows 7 has DX11 installed.
When I try and start either single or multi-player I get an error dialog that reads:
"The program can't start because d3dx9_34.dll is missing from your computer. Try reinstalling the program to fix this problem."
I note on my old XP partition that d3dx9_34.dll is installed in C:\Windows\System32.
I get the impression that I HAVE to install DX9 even though I already have DX11 installed ?
Does this make sense ?
Will installing DX9 cause any known conflicts with DX11 ?
Is there a DX11 compatibility pack required or something ?
