i hope this is the right topic.
So i had the problem when starting the epic games launcher that nothing happened after it updated it. But i needed unreal engine 4
So i build it from source code with this manual: https://wiki.unrealengine.com/GitHub_Setup
I then tried starting UE4Editor.exe but it crashed without error or showing up.
After some research i found out it crashed in “UE4Editor-XMPP.dll” at the function “sha1_block_data_order”.
So i thried to fix the error and managed to get it to work.
I just did this:
- I opened “\Engine\Source\ThirdParty\OpenSSL\OpenSSL.Build.cs” and replaced all ocurrencies of “OpenSSL102Path” with “OpenSSL102hPath” where “Target.Platform == UnrealTargetPlatform.Win64”
- After trying to compile UE4 it returned an error. I just needed to rename “libeay32.lib” to “libeay.lib” and “ssleay32.lib” to “ssleay.lib”
After that i can start UE4Editor. Maybe te same problem is in the Epic Games launcher. I hope this helps someone.
