Cuda Collision Solver Not Working

[heekma]

You need CUDA 11.2.2, not (necessarily) the more recent versions.

Try temporarily renaming this folder:

Code:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA

to

Code:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA_tmp

So that Max can't find the newer DLLs you installed and instead reverts to the one included in the tyFlow CUDA DLL zip which you placed where tyFlow is located. Then restart Max and see if you get the same error...

 Thank you for your help.  I copied the DLL files to the max root, that seems to have fixed the issue.
