UE4 Installation keeps failing, file corruption?

I have been trying to download UE4 for a couple days now, and while the Epic Games launcher goes up with no issues, the download always ends after looping with a message “Install failed: The installation is corrupt.”. I’ve Googled it, and found people with the same issue, but I haven’t been able to fix it. There are multiple lines like this in the logs:

[2016.01.17-20.13.14:486][ 0]LogStreaming:Warning: Failed to read file ‘…/…/…/Engine/Plugins/Messaging/MessagingDebugger/Content/GroupBorder.png’ error.
[2016.01.17-20.13.14:486][ 0]LogSlateD3D: Could not find file for Slate resource: …/…/…/Engine/Plugins/Messaging/MessagingDebugger/Content/GroupBorder.png

I am an admin on my PC, and I use Windows 7. Any help would be much appreciated !

EDIT : Full logs

Nothing? Kinda hoped someone would help out a bit.

Did you look for those files?

I have, but it doesn’t seem like they manage to download.

Hi Solstine,

I apologize for the delayed response. Could you attach a DxDiag for us to review?
