Hi Allexia,

  1. While installing did the user run setup.exe as admin?
  2. Clear the cache of the Fluent application by renaming the Ansys folder to Ansys.old (type in windows search bar %appdata% or C:\Users\username\AppData\Roaming\Ansys), rename .cfx and fluent.conf folder(C:/Users/username) and relaunch the application.
  3. Can you please check if any antivirus/ security software is blocking the Ansys application?
  4. Can you please ping and telnet the server using the command prompt? Send Snapshot.
