I really want to know how to fix the problem on my laptop of installing cuda_9.1.85_windows.exe on a Windows 7_x64 system. After choosing the insallation derectory an error window comes with “Non 7z archive” with the title “cuda setup package:error”. I try to update the driver of my NVIDIA GeForce GT 720M but it seems doesn’t work. Can anybody help me to solve this problem?
Thanks a lot!
