Running with 2 MPI processes. There are 2 MPI processes running on the same node as the root process. This binary does not support OpenMP threading

Dear All
I have recently updated Materials studio 2016 to my windows machine. We have a licence for CASTEP and ONETEP as well.  It works absolutely ok with CASTEP using single core along with parallel calculations but with ONETEP, It does not work  for even a single machine.   Please update me what to do. here i have copied the warning .............

Thanks 
Faruq
