Hello fredrikberg. Seems that AA CUDA Bridge can not see Nvidia CUDA Toolkit. I had the same problem when I install it first time into my x86 XP OS. CUDA Toolkit must be installed into C: not into programs files folder.
Uninstall AA CUDA Bridge and Nvidia CUDA Toolkit and try it again installing Nvidia CUDA Toolkit in C: and AA CUDA Bridge in the correct NebulaTempRepository folder

Thanks for helping me out, but I´ve have tried that now a couple of times and it still doesn´t work.
One thing i have noticed is that there is no cudart.dll file anymore since CUDA version 3 I think. It´s now called for example "cudart64_31_9.dll" I have tried to copy it to VST/Acustica folder and also renaming it to "cudart.dll" which some other users of other CUDA programs have done with success.
