Unreal Engine 4 Launcher crash

When I run unreal engine launcher, this message continuously occurs.
'The following process has crashed: UE4-EpicGamesLauncher
we are very sorry that this crash occurred. (…) ’
I want to solve this problem. My computer is window 7 and unreal engine version is 4.6.1
Please help me.

Hi Moondance. Sorry about that, could you up the following folder and attach please?

C:\Users\username\AppData\Local\EpicGamesLauncher\Saved\Logs

thanks for your reply.
I found that route. There is a only text file in that logs folder. You mean that text??

I attached the text file. I look forward to your reply.link text

I’m afraid that doesn’t look like an EpicGamesLauncher log. Could you double check you went to the right path? Perhaps attempt running the launcher a few more times too first.

You should see a list of files named like “EpicGamesLauncher.log” and also a few like “EpicGamesLauncher-backup-2015.08.10-****.log”

If not then perhaps a screenshot of the crash window that you see might help

I will try it and if I have problem, I’ll tell you. Thank you.

I attached file. Is it right?? I expect your reply. Thank you.

Thank you Moondance!

It appears as though you have been effected by a bug where incorrect data goes to the vault’s data cache. I can see that a “UE_4.7” folder is probably in there but it shouldn’t be. I believe removing it should stop your Launcher from crashing.

You will see that folder here:-
C:\Program Files\Epic Games\Launcher\VaultCache\

It runs well !!
Thank you so much!!

I have exactly this problem occurred. I had tried all solutions which you shown up. But nothing done. But in the last answer, there was a path like:"C:\Program Files\Epic Games\Launcher\VaultCache". I have Launcher folder but there weren’t any folder named ‘VaultCache’. Please help me about this problem. And sorry for my language.

I have founded it’s solution. It was occurring because of my bandwidth. My bandwidth is too less to download that launcher. I had a broadband (Reliance) plan with 512kbps link speed and download speed was only 50-60kpbs so…
But now it working nicely.
Thank you.
