Bootcamp Error Windows 10 Need 64 Bit

[imac abuser]

Hey Guys I'm trying to install Windows 10 Home via a USB drive onto my Mid 2015 5K iMac. I'm not new to boot camp but I'm getting an error saying "Need 64-Bit Windows installation USB drive or DVD."

I'm looking at the box and it says 32-bit/64-bit but for some reason I can't get to the 64-bit so I'm stuck...

My iMac is on 10.10.5 and my Boot Camp is 5.1.4 HELP PLEASE!

I figured it out, if you go to https://www.microsoft.com/en-us/software-download/windows10ISO you can download the iso file for Windows 10 64-bit and then burn it to a DVD.
