  What Linux version do you have installed? Please share the output of the command /etc/*release
  Could you please try referring to this post for some suggestions?

  You may also want to try a silent install to avoid the issue.

  CentOS 8.5 is unsupported and untested. Please refer to our supported platforms page: https://www.ansys.com/it-solutions/platform-support
  Have you tried running a silent install and ensuring all prerequisites are installed?
