Trying to update to 4.2.1. Launcher downloads with great performance, until around 360 MB are left. Then it gets stuck at 0 kb/s and fails. I enabled HttpLog in the config and notice that it fails to download a specific chunk. It is not even possible to download it directly in the browser.
I am sorry to hear that you are experiencing this issue, and I will begin investigation into this as soon as possible. Thanks for your patience.
In the meantime, and for best results, please be sure to review our suggestions for how to report your issues, and feel free to edit your post if you have any additional information to provide:
Hi Eric, thanks for your response. I’m on 4.2.0. trying to Update to 4.2.1. I get the standard Install Failed message, after it has waited at the missing file until timeout.
“Install Failed, Could not download patch data. Please try again later.”
Increasing timeout doesn’t help. It only changes how long the launcher sticks at 0 kb/s and repeats the ERROR in the log.
To add information to this problem:
I am on Windows 7. Using the installed version of the Launcher (not compiled). Desktop PC. (Intel Xeon 2.6 GHZ, 32 GB Ram, NVIDIA Quadro K2000 4GB)
Had you originally patched 4.2.0 to 4.2.1 before the official Launcher version was released? If you were using the 4.2.1 Hotfix preview, please make sure to remove the applabel: -applabel=Production-HotfixPreview421 from your launcher.
Just to confirm you have gone into “C:\Program Files\Unreal Engine\Launcher\Engine\Programs\NoRedist\UnrealEngineLauncher\Config\DefaultEngine.ini” and added:
That was one of the first things I tried and the only thing that happened was that it took longer for the error message to appear. I did it again, just to triple check, and the launcher stops at the same file.
Edit*
You don’t have to hurry to find a solution for my sake. We decided to go with a compiled version of 4.2.1 until 4.3.0 is released, hopefully the launcher issues will be gone for us then.
Very glad you guys are unblocked. Stick with the compiled version for now since it has you unblocked.
Also, can I get some additional details about your environment? Looking for dxdiag from the machine or machines having the problem. Also any details about the network environment you are on. i.e. standard home modem and router or office environment with additional firewalls, routers, vpn, etc.
I’ll email you directly and we can swap info from there,
