Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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


After having problems with the launcher update being stuck at 80%, I replaced the .exe with the QFE that was released and it went straight into the launcher without an update...Now it only says syncing your account and after a while download error, retry? After clicking retry it just keeps saying Please Wait... Is this a bug or is it because of slow download speeds?

OS: Windows 8.1

Hey! Sorry didn't see your extra post here. Probably easier for us to work through your issue here instead as the other posts are getting a bit noisy.

Your log shows you retrying the downloads - and one time, you nearly got them all ok, and only the UE4.0 manifest did not succeed.

I asked on the other post, what you currently have in your DefaultEngine.ini for the HTTP setting, could you reply here instead :)

I'm so sorry for the late reply! :( In their respective order 720, 2000, 2000

Will it work if I try downloading it at a faster network? I'm currently having problems with my home ADSL.

Hey Boompit! Yeah you should have much better luck on a faster network

avatar image Boompit Mar 23 '14 at 07:15 PM

Wow that was a fast reply! :) Thanks a lot for your great support to me and the others! Your Epic! (literaly... :D) I'm itching to use the most awesome engine ever! :)

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:


Let me know if that helps!

Hi Leigh, Yes, that seems to have done the trick. Thanks a lot.

Ok so quick update.

I upgraded my internet speed and although it showed 0mb/s download speed I could see the download size reducing from 80MB to 40MB and finally installing. And its done!

Great news JZAcH. Are you running OSX or Win? OSX has a known UI issue with 0B/s, but if it's Win i will have to investigate that too :)
