[Pw_forum] Unable to Successfully Install Parallel Version of QE on Windows

[Suchit]

Hi Axel,

Good idea! QE-5.3.0 from the site you provided (after uninstalling the one
that I had installed from QE site) didn't work either. However, QE-5.2.1
from both the alternate site as well as the QE download site successfully
runs an SCF calculation in parallel. All these tests were performed with
the 64-bit MPICH2 versions.

Thanks,
--Suchit
