"Fatal error occured (5): null" when starting minecraft :(

#1 Posted by Dedodido (235 posts) -

Ok, so I just found out about this piece of genius, but when I try to run it to give it a go, I just get this message saying: 

Failed to Launch
 
Fatal error occured (5): null
Extracting: lwjgl.jar.lzma to lwjgl.jar 

I've tried deleteing the files under appdata and re-launching, as well as reinstalling java, but to no avail.
 
Does anyone have any ideas?

try the other exe on the page.

Managed to sort it in the end by running the exe on a different PC to download the files and then transfering them over. Still pretty weird though.

@Stagger: Try deleting Minecraft.exe and re-download it.

I fixed it by downloading the other .exe.
 
Minecraft: The Other Exe.
 
Yup. I had to do it.
