I think the image is not clear enough, so I type the command here:

depends.exe /c /f:1 /pb /pp:1 /pg:1 /ot:Log.txt “C:\Program Files (x86)\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe”

I think I found the solution.

With this tool, I get that XINPUT1\_3.dll is error for my computer. So I backup it and install the newest DirectX and it works.

Today I installed Epic Games Launcher and get a 0xc000007b code. I google the answer here:

However, when I follow the instruction and run the depends.exe，I get nothing  
280105-  
And there is no Log.txt in the folder.

I tried every method that others may meet in the answers, such as backup the dll and reinstall DX but it doesn’t work.I will appreciate everybody who can give me some tips to fix it.
