I just installed http://www.open-mpi.org/software/ompi/v1.6/downloads/OpenMPI_v1.6.1-1_win64.exe on our Intel i7 64-bit Windows 7 system.
When I try to run some executable, I am getting error "Application Error The application was unable to start correctly (0xc000007b)..."
Any help please ? The "C:\Program Files (x86)\OpenMPI_v1.6.1-x64\bin" string is in my %Path% variable.
PS: On 32-bit Windows 7 the 32-bit OpenMPI application works fine.
