Bootcamp Assistant not working for Windows 10

I picked up my new macbook pro this morning (13 inch 256GB), and I've been trying to dual boot it with Windows 10. I've downloaded the ISO from Microsoft and formatted my USB stick to FAT. However, I keep getting errors in the bootcamp assistant. It either gets stuck while downloading the Windows Support files or says the Windows Support files could not be saved to the selected drive.

Any help?

MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.5)

Now BCA is beginning to provide BC6 drivers on the OSX side as well.

Alright, I tried downloading the support software through BCA again and it still hangs. After looking at activity monitor, it seems like BCA doesn't even download anything.

However, if I stop the download when it is stuck, reopen BCA, and try to download the support software again, the download seems to go by in just a few seconds but then I get the error message: The Windows support software could not be saved to the selected drive.

1. Try a wired connection, if wireless gives you an error.

2. Run Disk Utility and Repair Permissions and Disk.

3. Test BCA download. Choose only the Download Software option as a test.

Turns out that BCA never was really getting stuck. I let it sit for about 6 hours, came back, and it had finished. I've got windows 10 fully running now.

Did it take 6 hours to complete the installation locally after the Windows Support Software download was complete?
