I have no problems with my simple cufft software using 6.0 on many user installations, but with 6.5 I can’t get the software to work on systems where the 6.5rc has not been installed.
As part of my software I’m copying cufft32_65.dll and cufft64_65.dll as appropriate to the target systems, no other DLLs.
Nothing works - not even the basic cudaGetDeviceCount() which returns the error “CUDA driver version is insufficient for CUDA runtime version”.
The system I’m testing is Windows 8.1, GTX 630, GeForce 337.88 driver. I guess I missed something in the 6.5 rc release notes?
