Thanks for the info. As far as I can tell, all the NFS filesystems are mounted async, which is the CentOS default.
I am confused by your "set export async" & other "set" commands at the end of your message. They don't seem to have anything to do with shell/bash
I deleted the ~/.ansys, ~/.mw and ~/.config/Ansys directories and tested ANSYS 19.2 again, but got the same results.
Even if licenses were not available, why would it throw JScript runtime errors?
Any other ideas?
