[Newcomers Readme!] How To Install UE4 From The Launcher

Hello guys, I am stuck in a “please wait” message, please see screenshot:


Edit:
My connection is slow atm (384kbit/s), but I let it in the above state overnight, and ProcessHacker stated that just ~20MB was downloaded in that time.
Edit2:
I am on Windows7.

Edit3:
after signing out, and re-entering password, it gave me the option to click “install” in the yellow outlined box! Let’s see how it goes from here.
Edit4:
it finally started now, I read the hint that some restarting helps, but I feel like signing out so you need to re-enter password, was important too - so I let this standing here, in case someone else has similar trouble.
