Missing fatBinaryCtl entry point in nvopencl.dll

Post by sdean7855 »

When I try to start running Folding@home, I get popup msg: The procedure entry point fatBinaryCtl could not be located in the dynamic link library C:\WINDOWS\System32\nvopencl.dll

I updated my NVIDIA driver, and nvopencl.dll exists in that directory, dated today, 24.0 MB.
Reinstalled FAH, get same popup
