Tried that and got similar results! I first ran the mpiexec located in C:\Program Files\ANSYS Inc\v222\commonfiles\MPI\Intel\2018.3.210. That one gave me an error launching notepad. When using the MPI located in C:\Program Files\ANSYS Inc\v222\commonfiles\MPI\Intel\2021.6.0, it launched notepad just fine. That seems to me then that I need to change which MPI is used by ansys? How can I do that (and hopefully for the whole system, not just the current user). Thank you!
