Hi all, It has been quite a long time since the last tie I updated the MPI's version of the Windows version of my software (I am using still using MPICH 1.4.1). I am having many problems regarding folder permissions and credentials using Windows 8. I went to MPICH's download page and I understood that MPICH's group no longer supports Windows distribution because it now points to Microsoft MPI homepage. Is this correct? Regards, Luiz
