I do not remember exactly what modification I did on my computer, but when I tried to open the UE4 the following error appeared:
(image taken from the internet)
It is not the first time that this error occurs, but there I went to solve it again (If I remember correctly I deleted the folder with the libraries (.dll) that resolved it the first time, so I had to download it again):
But before, a poetic pause... One day Albert Einstein said: Insanity is to keep doing the same thing and expect different results.
So this time I looked for another place to try to solve this error, :
(VIDEO LINK) => https://www.youtube.com/watch?v=kA4N0x4iG54
In this video the man orders to download a compressed file that contains three folders.
(COMPRESSED FILE) => http://www.mediafire.com/file/at50mz3rkobxe4i/Erro+0xc000007b.rar
You should copy all libraries from the first folder and paste them into the sytem32 folder (if your system is 32-bit) and the system32 and SysWOW64 folders (if your system is 64-bit).
Your pasting must be of the type that replaces existing files:
You will need to give administrator permission for the computer to do this:
There will be an "error", you select the "do this for all current items" box and then click ignore:
Once you click Ignore you will notice that there are numerous selected files. Press the delete key and enter to delete them (again you will have to provide administrator permission):
NOTE => For users of a 64-bit computer, you will have to do this in both folders (system32 and SysWOW64).
In the second folder of the file that the video man made available has the directX installer. I RECOMMEND NOT TO USE, BECAUSE WITH ME IT DID NOT WORK. I even had to reinstall directX.
(OFICIAL LINK OF DIRECTX) => https://support.microsoft.com/pt-br/help/179113/how-to-install-the-latest-version-of-directx
Just install DirectX.
In the third folder of the file that the video man provided, there is another installer (all versions of Visual Studio) that also did not work for me.
(OFICIAL LINK 64-bit) => https://www.microsoft.com/pt-br/download/confirmation.aspx?id=36805
Sorry, I downloaded 32-bit too, but I can not find the link.
Just install all versions of Visual Studio from Microsoft.
The video man also provides a link so you can download the three folders separately, so you only need to download the first folder: http://bit.ly/2CI3kse
That way I killed two birds with one stone.
The lighting build works and the error has been fixed.
