Weird DirectX Issue

[Novek]

My Windows Vista & XP installs have a odd issue with DirectX

On Vista, Programs WinSAT & Dreamscene keep crashing due to dll d3d9.dll

On Windows XP the only issue I've had is with camtasia studio but i can turn off DirectX accelerations and it works fine

I've tried swapping out the ATI card that came with my computer for the NVIDIA one but still same error

On Windows 7 & up this doesn't happen

Is directx_Jun2010_redist installed?

Windows 7 doesn't use dx9 on desktop (maybe Camtasia uses dx11 on Win7 too), check if directX9 works there with any directX 9 game, look up games you happen to have on pcgamingwiki

Camtasia Studio works fine now but only after closing it does it crash

Is any of the extended kernel-like stuff installed?

No

For dreamscene try installing K-Lite Codec Pack 16.6.5 (I believe someone reported some issues with a later version)

Is explorer.exe still crashing, if not I think it's Camtasia's own problems at this point

So now that you have the codec pack, launch MPC-HC that got installed with it and try to play a h264 test video

launch LAV splitter video settings - the red icon in the system tray, there is a "Hardware Decoder to use:" in the top middle, test various hardware decoders and check which do and don't work, make sure H.264 is checked under codecs for HW
