Error extracting natives: unexpected end of ZLIB

[Dylzan317]

My friend gets this error whenever he tried to run the DW20 1.6 pack, he is using Windows XP 32bit. I am going to try and get a pastebin of his console on here to help you, but do you have any ideas what the problem is?

The game suck 1,5g ram and we 32bit users are no avaliable to play the modpack atm. I think its something with the script cause i can make singleplayer game and run on 2-300 ram use and after few min it raise up to 800 and then crash when its over 1g. And when i try to restart it wont start cause i run out of memory. Only way to use the modpack atm you need 64bit, cause thats the only way to raise the memory usage in the game. So i think we just have to wait till they fixed the problems.

I also have problems with playing FTB 1.6, the game closes everytime without any warning or something. I run windows XP 32bit also. I think this is a problem and they will fix it soon.

You need 64bit so you can up your Ram above 1gig. Most definatly your problem.

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.

unexpected end of ZLIB usually means the download didn't complete successfully and you only have part of the file.
if you can post the error log, we can check for sure.

in the mean time, here are the SHA-1 Hashes of all the natives for the 1.6.4 Modpacks:

you can use WinHasher to verify them. (the Binaries w/o Installer option basically means portable)
