Do you have Aspen installed on the same machine?


The issue can be caused by Intel MPI dll files placed under C:\Windows\System32 by ASPEN V11.0 which is conflicting with the Intel MPI libraries of Fluent.
To resolve the conflict either update ASPEN to V12.0 or Run these commands from an Admin CMD:
