What do I do if the download gets stuck at 80% with the QFE installed?

Hey all,

For those still seeing issues like this even with the QFE(2) patch, please also try these steps, there is an extra HTTP timeout that can be increased for users with slow connections.

Locate DefaultEngine.ini

C:\Program Files\Unreal Engine\Launcher\Engine\Programs\NoRedist\UnrealEngineLauncher\Config\DefaultEngine.ini

Add to the very end the following four separate lines:

[HTTP]
HttpTimeout=600
HttpConnectionTimeout=180
HttpReceiveTimeout=180
HttpSendTimeout=180

Let me know if that helps!
