Hi i’m receiving this error… now what’s the problem?
Thank you 
what does the crash log say?
your asking the community what a crash code means when we dont have the codes, dont work for epic, and you didnt provide details. many times the community can help with a crash but you need to provide information to work with. even if we did have what the codes meant it probably just points in the right direction by telling its a memory fault or something. so we need to know the context in which the error occurred to be able to try to solve it.
Just needed a restart. all working good….
Thank you!
Have a nice weekend
I’m getting the same error while trying to launch 4.20.3. It just says failed to install prerequisites but they’re all installed. Grrr.
Answer from Cipher 5 - add " -SkipBuildPatchPrereq" without the quotes to the launcher shortcut and it will skip the pre-reques check if you’re still experiencing the issue after rebooting like I was.

Yes after restart my problem was gone to!
How do you restart ? Thanks.
I’ve just reboot the pc.
same error code her, but as said, I just restarted the pc and the editor launched just fine.
Doesn’t work for everyone, hence my answer is for those who still have the problem after rebooting.
try to download the instalation file again.
Open the epic game launcher. click the library on the left side.
the you must see Engine Versions.
See if you see launch or install.
The download process takes a while and i have a 100 MB internet connection.
Hope this helps.
That’s more than unnecessary. If you just disable the prerequisites like I said, then it works fine without a re-install.
its just a litle BUG, dont have ANY LOG, just a CODE what we dont find NOTHING in ALL documentation. Start u project by Ue4.exe… have a icon in your desktop, no? Probably yes. Look at that!
Have a CODE, dont have a LOG. Talk with UE4 dev about a CODE without ANY log, not with community…
In real dont need reestart, just inicialize the ue4 from exe.
good luck.
Start from ue4.exe, not by launcher… after it, just instal what u want instal, download, and add to u project. its look like a BUG.
Dont need reestart. Just START the ue4 by .exe NOT by the launcher. Its or is a BUG. Launcher dont recognise some times the ue4.exe.
First, dont need ‘reestart’…just START the Ue4 from .EXE Its a BUG. After that, just download what u want, need, etc…and ad at u project. Is it, dont need reestart every time.
And yes, EPIC Game, FIX it!
you’re right, just ran the executable (through the icon on the screen) and it works just fine. No restart necessary Thanx
I meant on desktop* (accidentally wrote “screen”)
