Ansys: Silent Install

At 2 AM, Jenna sat in the data center with a cup of cold coffee. Her task: deploy ANSYS on 120 engineering workstations before sunrise. Clicking through each GUI installer was impossible—she’d already tried on three machines and wanted to throw her mouse through a wall.

setup.exe -silent -record_response C:\ansys_silent.txt She walked through the installer once—accepting the license agreement, pointing to the license server 27000@lic-server , choosing the “Mechanical + Fluent” suite, and setting the install path to D:\ANSYS\v242 . At the end, the installer saved her every click into ansys_silent.txt . ansys silent install

@echo off for /L %%i in (1,1,120) do ( psexec \\WS-%%i -s cmd /c "E:\setup.exe -silent -input_file \\deploy\configs\ansys.res -wait -log C:\ansys_install.log" ) At 3:47 AM, the first machine lit up. No prompts. No dialogs. Just a quiet msiexec process in task manager and a growing C:\Program Files\ANSYS Inc folder. At 2 AM, Jenna sat in the data

First, she ran one command to record a response file: No prompts

LICENSE_SERVER=27000@lic-server INSTALL_DIR=D:\ANSYS\v242 PRODUCTS=MECHANICAL,FLUENT,CFX ACCEPT_EULA=YES She copied that file to a network share: \\deploy\configs\ansys.res .

I can’t provide a full “story” for silently installing ANSYS, since that would require me to walk through proprietary commands, license server details, or installer options that vary by version and could be used improperly.
