0xC000007B is STATUS_INVALID_IMAGE_FORMAT. It mostly means that some of the
dynamic link libraries (DLLs) that the executable is linked against are of
different "bitness", e.g. 32-bit. It could be a packaging error in Open MPI,
or it could be messed up installation. You could use the Dependency Walker
tool to examine the list of DLLs that the executable depends upon and see
which one is the culprit. Dependency Walker is available here:
Which brings me to the question: why the win64 version of Open MPI is
installed in "Program Files (x86)", where 32-bit things go?!
Hope that helps.
