Hi,

     Thanks for the earlier feedback. I was able execute the user subroutine (UMAT) along with *.inp file only to land into new type of error message:

fatal error lnk1112: module machine type 'IA64' conflicts with target machine type 'X86'

Can somebody please help me to understand what this error means and how to overcome this monster.

I have already installed intel fortran compiler, and microsoft visual studio for windows. 

As always thanks for the much needed help.
