Start fails,Missing fatBinaryCtl entry point in nvopencl.dll

Post by sdean7855 »

Running Folding@home and 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 for my GeForce GTX 950 video card; nvopencl.dll exists in that directory, dated today, 24.0 MB.
Reinstalled FAH, get same popup

Use Disp[lay Driver Uninstaller or similar to get rid of the Nvidia driver.
Run CCleaner and scan/fix everything, including the registry (make a backup of what you are erasing).
Reboot.
Reinstall the Nvidia Driver.

Does that fix it? If not.

Check your firewall software isnt sandboxing or virtualising FAH. Also make sure it can connect to the internet.
Try an older version of the Nvidia Driver.
