how to get solidworks 2015 SP5 installer

I am trying to install the Student Edition 2015-2016 on a Windows 10 machine that has the SP2.1 installer, how do i get the SP5 installer. Apparently the SP5 supports Windows 10. I do not have access to downloads that requires a subscription. Also, how do i contact submit a Service Request to SOLIDWORKS Technical Support.

Thanks.
