Silent Install Powershell Popwindow

Question

I am trying both using exe and msi to install .NET 4.8 but still the pop up window comes up. I tried all the syntax what has been provided here for silent install but none works.

Start-Process -Wait -ArgumentList "/Silent" -Passthru -Filepath "=============\filename.exe" Start-Process -Wait -ArgumentList "/Silent" -Passthru -Filepath '=============\filename.exe' Start-Process -Wait -Filepath "=============\filename.exe" -ArgumentList "/S /V /qn" -Passthru

Anything I try nothing works. I have seen several users have had problems in the past and why is it something it is not resolvable? Any suggestions? I am sure it should be possible to install through PS or batch file. If I try using the batch file I get a WINDOW popup for msiexec.exe

Any suggestions it is simple install of .NET file from the network location.
