I have installed the latest Student version of ANSYS AIM 18.2 and even though I have followed the installation steps and my pc fulfils the requirements, I get the attatched message.

Please note, that my installation folder contains no special characters (I have already checked the respective thread) and I have uninstalled and reinstalled it twice. I had the same error when trying to install an official licensed version of ANSYS 17.0, provided by my University.

I googled the message, but it seems that nobody else has encountered it before. I cannot even find any information about what "AFD Rules files" are.

Thank you in advance.
