So every time I go too run this modpack I get this message. I am on a 64bit operating system so I don't know what to do.
The message is "error extracting natives unxpected end of ZLIB input stream"
So I get this same problem however I am operating a 64 bit not a 32bit. I am trying to run FTB Horizons and when I am mid download it just says error extracting natives. :(
