Also the same here. 3GB 1060s can not start ETC, ETH fine. Once - eres solved, then no result, only error message.
One interesting thing, maybe a Windows techie can figure out something (I guess ir is Windows issue).
I run mixed rig of 3x1050s (4GB) and 3x1060s (3GB). I set up EBWF for ZEC for the 1050s only and Claymore for ETH for the 1060s only, on the same rig. If I start Claymore for the 1060s, it creates DAGs and starts mining, then I start EBWF, 1050s start ZEC and everything is good. But if I start EBWF for ZEC, then I start Claymore for 1060s,I get the same error message fir one 1060, always the same one and always for only one, Claymore dies and tries to restart, running into the same issue, loop.
