Boot Camp problem

Hi,

I have Macbook Air 13″ Early 2015 running El Capitan 10.11.1 and fully updated. I have been trying to install Windows 10 (original iso from Microsoft) via Boot Camp almost a week, the first problem i got is that the Windows Software files can’t be downloaded because of a network problem.

Now I have a different problem, each time that I’m trying to install I’m getting this error:

Thanks,

Mike
