downloading windows support software

I am trying to install windows 10 by using bootcamp on my MacBook pro 13 early 2015 with OS X El Capitan but with little success.After selecting the size of the windows partition a loading screen appears with "Partitioning disk" which after a while changes to "Downloading Windows support software". At this point it gets stuck. I have tried several times but nothing changes.

I do not know what I am doing wrong and i would appreciate any help, Thanks.
