i have troubles with sgminer and spreadminer from this topic
maybe x64 is the reason ?
"I have troubles" doesn't really tell much and I don't know about the sgminer version but I'm happily running the CUDA miner on Win 7 x64 so that probably isn't the problem.
sgminer crashes at start
i tried on x32 & x64 win 7
7970, catalyst 13.12 & 14.4
the same result
