How does a .exe file read instructions from a file

Hi Team,

  1. I have an installer xyz.exe

  2. While installing the products through the UI of the installer, I have chosen the option to make a script, an added feature provided with the installer itself.

  3. The products are installed successfully.

  4. The products are now uninstalled & I would like to use the same script to install the products. But this time I want to do it via command prompt or powershell.

  5. The script is in a file in my Desktop.

  6. How do I pass the script file to the xyz.exe in the command prompt so that the products are installed.
