Can't download the software because of a network problem

Hi all i am using the MacBook Pro (Retina, 15-inch, Late 2013),
I am trying to install Windows 10 with the version downloaded through the Microsoft website.
I have finished downloaded it and am trying to use Boot Camp to install Windows 10.
However i faced an issues and it is that it 'Can't download the software because of a network problem'.
I am stuck here for an hour and i can't find any solution.
I have done everything right till now by following online tutorial but this is preventing me from continue.
Any help will be appreciated.
Thank you.
