I've had success with version 3.0, running at 2900 H/s on 6x GTX 1070Ti's, but the version 4.0 code silently fails and immediately exits without any output.
I am running: Windows 10, Nvidia driver ver 23.21.13.8813 (10/27/2017).
Not sure what, if any other info you'd like, but I'd be happy to assist further.
I'm happy to help -- just wondering how did you run the miner?
My guess is that your command line parameters might be off. Can you try directly click on bminer.exe and to test whether it works?
Thanks.
