Trouble installing Unreal Engine launcher on Win 8

I manage to use the unreal launcher installer and everything goes fine, up until I click the launcher icon and grey box with “Epic Games Launcher - Please Wait” stays, not doing anything.
I even left it for a few hours once, only to have to close the not responding program from Task Manager.

The DxDiag and Logs are in the .zip file.

Hi Gabriel93,

Try the troubleshooting steps in this section of the troubleshooting guide. Specifically, please add the following exception:

xmpp-service-prod.ol.epicgames.com port 5222

If nothing works, follow the steps here to generate your Debug Logs. Post them here, along with your Dxdiag/system specs.

Hi Leebowitz,

Thank you for the help. It turns out all I had to do was add " -http=wininet" in Epic Games Launcher Properties/Shortcut tab. Everything works fine for me now. Downloading Unreal Engine 4.10.1 as I type!

Once again thank you,

Gabriel
