When trying to silently install an MSI via PowerShell using this command:

Start-Process $webDeployInstallerFilePath -ArgumentList '/quiet' -Wait

I was getting the error:

The specified executable is not a valid application for this OS platform.

I instead switched to using msiexec.exe to execute the MSI with this command, and it worked as expected:

$arguments = "/i `"$webDeployInstallerFilePath`" /quiet"
Start-Process msiexec.exe -ArgumentList $arguments -Wait

Hopefully others find this useful.

You can use   msiexec  i  c  package msi    You can also add some more optional parameters  There are common msi parameters and parameters which are specific for your installer  For common parameters just call msiexec

In powershell 5 1 you can actually use install-package  but it can t take extra msi arguments  install-package   file msi  Otherwise with start-process and waiting  start -wait file msi ALLUSERS 1 INSTALLDIR C  FILE
