OpenCL bug 0.2-10: i could reproduce it on my rig by using exotic characters in the path where JCE exe was, and this case is fixed. But there may be another cause of bug. Did you use non-english path too?
DEV BIG thanks! it all worked
I did not immediately understand that it was necessary to avoid Russian letters in folders with the JCE program!
as sample d:\JCE _MONERO\033b6\ all work nice!
as sample d:\MAЙHEP\033b6\ error
