"request" is a rather strong word. i hope you mean to "kindly ask".
have you checked whether your executable is 64-bit (likely these days)?
and whether the libraries are 64-bit as well or 32-bit (likely in /usr/lib)?
having the file doesn't mean that you have a _compatible_ file. the
dynamic linker will reject and incompatible shared library.
