Hi!
My Nuendo 13 suddenly cannot handle any iZotope plugin window. “D3D9.dll” becomes unstable. Also, iZotope RX Audio Editor crashes as soon as it opens. Anyone else gotten these problems? I’ve tried to reinstall RX and DirectX but on Windows 11 it’s not so simple. How can I fix the d3d9.dll file???
Open an admin level command prompt and enter SFC /SCANNOW. It will look for missing or corrupt system files and replace them if possible. Once complete it will tell you if it found any and whether it was able to successfully repair them.
I suggest running the command twice as it often finds a few more the second time around.
Ah, okay! Will attempt this method.
That’s Direct3D. Chances are, the problem originates with your GPU. The error only surfaces in D3D.
Do you have a discrete GPU in the PC?
Either way, I suggest updating your GPU / Video drivers. If you have an NVIDIA GPU, their Studio drivers (or whatever they are called right now) tend to be better for DAW usage vs the game-optimized drivers.
When you say “suddenly”, what else has changed in the meantime? Updated Nuendo build? Updated iZotop plugin? Monitor changes? Something else?

Hi Pete!
I suddenly remembered what made this bug appear for me earlier, years ago. It was a GPU tweaking software extension called RivaTuner Statistics, which sometimes and somehow causes a conflict with d3d9.dll access, when iZotope’s interfaces try to use that same DLL. This issue had plagued someone else as well so I ran into it through Google. So, getting rid of RivaTuner helped me again.
