Hello, I’ve just installed UE4 and when I try to run the Epic Game Luncher I get the 0xc000007b Error. I’ve already tried to fix the problem with DWalker as suggested in other threads but without suggess. You can find my log at the end of the post (some texts are in Italian, I hope that it’s not a problem since most of the terms are similar to english),

I tried to unistall and reinstall VC2013 but again without success.

Someone can help me?

Problem actually fixed:

SOLUTION If someone need it:

Download d3dcompiler_43.dll download the right version 32 or 64 bit,

Make a backup of your old d3dcompiler_43.dll

Replace the new DLL in C:\Windows\System32, test if it works…

During installation I 'v got same error, my machine is Win7x64, first time during installation got error

There is a problem with this windows
installer package. A program run

supportpersonnel or package vendor

I tried suggestions from here like SKIP_DIRECTX=“1” and run as administrator and from here to reinstall VC Redist 2012 and VC Redist 2013 both x86 and x64 versions non of above helepd me. Will attach log, this same error happened to me when I was putting wrong version of DirectX .dll file, for ex. needed x86 and I placed x64 version in root dir of app. Here is my log

Thank you for the help but it didn’t help me.

I tried more and more time reinstalling VC2013 / 2010 / 2008 and tried again to run DWalker to see if the log changed… At the end a problem with d3dcompiler_43.dll appared… So I simply searched it and downloaded it… Now it seems to work.

Hi swissmistery,

From your log file it looks like you are using Windows Vista. This is a unsupported operating system.

Here is our recommended specs:

  • Desktop PC with Windows 7 64-bit or a Mac with Mac OS X 10.9.2 or later

  • 8 GB RAM

  • Quad-core Intel or AMD processor

  • DX11 compatible video card. UE4 will run on desktops and laptops below these recommendations, but performance may be limited.

You can find more info here.

Cheers,

TJ

Actually I have W7 64 bit…

Anyway I fixed my problem 1 hour ago, check my comment on my question.

Thank you anyway

That’s odd that the logs showed your OS incorrectly, I’ll look into that. Anyways, I’m glad you got it working.

Have a good day!
