Hi, hopefully this helps on the Windows 10 side of bug fixes for Grin31.
It seems that if there are spaces in the folder path, bminer quits with:
The system cannot find the path specified.
I had the miner working with two GPUs, but after Windows updated from build 1803 to build 1809 it stopped working with the following error:
[FATA] [2019-02-18T17:59:35-07:00] CudaError: Unknown error:C:\WINDOWS\System32\bcrypt.dll
[WARN] [2019-02-18T17:59:35-07:00] Miner died! It will be restarted soon...
I have another rig on build 1803 and it seems to be working.
I've also encountered OpenCL errors which are fixed by doing a clean install of the NVIDIA drivers.
