I am trying to install libre office quietly.
This successfully launches the installer:
Start-Process c:\temp\LibreOffice_7.2.7_Win_x64.msi
This doesn’t do anything:
Start-Process c:\temp\LibreOffice_7.2.7_Win_x64.msi -ArgumentList “/quiet”
*.MSI file are not executables. You need to run msiexec.exe and provide the *.MSI file including some proper command line options to install a software package silently.
Regardless of that - When you post code, sample data, console output or error messages please format it as code using the preformatted text button ( </> ). Simply place your cursor on an empty line, click the button and paste your code.
