Check in github source line in google search but still I am not be able to install the previous. Are you facing the error while run the miner program in your PC. I am asking this because the issue I am facing is that only. If the information shared to me. Even I rectify with your known ways to stop that. If you are unable to find the old version, check the graphics card and choose the software you should use it.
its just i can get some gtx 1060 3 gb really cheap and some people have proplems to run the latest version of nicehash with them so its up to finding an earlyer version if i take them or not....
