Thank you vary much for your answer Randy.

I installed AEDT following the steps you described.

I get an error:
However, if I run sudo yum install , it seems the package is already installed:
I attach the full lld output log in case it can be useful.

Also, I have (I think ) correctly inserted the ANSYS FLEXlm port number and Hostname for the licence in config file. However, I didn't find where to insert the ANSYS Licencing Interconnect Port Number.

Thank you Tomas
