Thanks for the help George -
I think the issue is further back, it looks like the Flexnet daemon isn't being installed when the Ansys License Manager installer is running.
I restarted the entire process and re-installed Ansys License Manager. The installer error log had the following error:
Error was encountered during the licensing configuration:
'/ansys_inc/shared_files/licensing/tools/bin/runlmconfig' terminated after 1 attempts with the following error(s):
Exit Code: 127
/ansys_inc/shared_files/licensing/tools/bin/linx64/ansyslm_config: error while loading shared libraries: libSM.so.6: cannot open shared object file: No such file or directory
Any ideas on why the file cannot be opened? I confimed that the file exists and that I have permissions - running everything with sudo.
