I am getting an error while trying to download the installer:
ERROR
The request could not be satisfied.
I have tried both the Account and Billing download buttons. I have tried right clicking and saving the link, which tells me - “Failed - Server problem”
Also I am using Chrome and have tried IE to no avail.
Any suggestions?
Thanks!
UPDATE:
Working for me now, awesome!
Many guys have those problems right at the moment, so I think epic games have some server problems. 
Just try it again in some minutes/hours and then probably it will work. For this users it was working after some time/clicks: https://answers.unrealengine/questions/29864/download-error.html
