This is working as designed; a 64-bit JRE can not load a 32-bit library. Your Eclipse download includes a small native library, so you must use a 32-bit JRE for a 32-bit Eclipse or a 64-bit JRE for 64-bit Eclipse.

But, what if the computer where I am trying to compile is a 64 bits one? Can I install JRE 32 bits on a 64 bits Windows?

Thanks

Yes. You just have to make sure that the JRE and Eclipse match. They must both be 32-bit or both be 64-bit.
