  Hi I'm currently running windows 11 using parallels 19 on a M1 MacBook Air (16GB of RAM and 8 core CPU). I installed Ansys student 2023 R2 on it and the workbench is working fine. The fact is that opening MAPDL through MAPDL launcher is not working. it starts opening MAPDL, but after it opens the command prompt for a second, then it closes and after nothing happens. Also opening APDL from its application gives the same error. Can you please help me?
  Thank you in advance
  This is the error I got:

  MAPDl is not supported on an ARM CPU.
  That being said, some people have gotten it to work.
