Hi,

I ran into the same issue doing a very similar analysis. This error is due to the license in use not suporting the random vibration analysis, try switchting to a licensing level premium or enterprise. If you are using a student license it should have run, please check with support then.

You can check more about this on the ANTYPE command section on the Ansys Help
