Exec format error on binary 64bit of 0.13.2

hello there
i’ve downloaded litecoin-0.13.2-x86_64-linux-gnu.tar.gz
but i got

./litecoind

bash: ./litecoind: cannot execute binary file: Exec format error

so i use the 32bit version now (and it works, of course)… but why that error even i’m on Ubuntu 16.04.2 64bit?

Linux 4.4.0-81-generic #104-Ubuntu SMP Wed Jun 14 08:15:00 UTC 2017 i686 athlon i686 GNU/Linux

It runs without errors geth and gridcoinresearchd, and bitcoind @ 64 bit.

is your OS 64 or 32 bit? what about i386 did you try that one? all depends on your setup…your running the wrong format for your system according to what it says…

did you compile it correctly?

how is your drive formatted? NTFS? FAT32? I want to say you need fat32 for litecoin and bitcoin because of how the blocks are indexed…not exactly sure on that off hand though
