Errors when running parallel in different versions of openfoam

Dear foamers,
Previously I installed of5 and of7 in my computer and it all ran well in parallel. However, recently I installed of8 and I can run solvers in parallel with this version, while I cannot run in parallel with of5 and of7. The error message is shown in the following figure. I guess it is due to the libMPI is changed. But I have no idea how to handle this problem. Do you have any suggestions how it solve this problem?
