I had just installed minecraft and i can run minecraft but when i hit the login button it gives me this message:

Exception in thread "Thread-3" java.lang.UnsatisfiedLinkError: /home/usr/.minecraft/bin/natives/liblwjgl.so: /home/usr/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

I have no clue what is happening. I researched online and nothing is helping me. I tried to force update minecraft several times and the same thing continued to happen.


Anyone know what this is?

Thanks

Minecraft is running for me!

By the looks of things I'd just say delete all of the Minecraft files and just reinstall.

I tried what you guys said but it is still happening. If this helps i run minecraft w/ java 7 runtime. The problem also occurs after i it login. The screen just turns black. I can run my server just fine (and other java programs) without any errors though. Do u think it could be a bug in the programming?
