Powershell Call MSI with Arguments

Question

I\'m working on a powershell script to install Autodesk products and I am having some trouble.

I\'ve tried this many different ways and keep running into errors.

Don't bother with Start-Process unless you need to run a process with elevated privileges. Use the call operator and splatting instead. The exit code of the command is stored in the automatic variable $LastExitCode.

$params = '/i', "$dirFiles\ABDS2017\Img\x64\RVT\RVT.msi",
          'INSTALLDIR="C:\Program Files\Autodesk"', 'ADSK_SETUP_EXE=1',
          '/qb!'
& msiexec.exe @params
$LastExitCode

Unfortunately you cannot tell msiexec.exe to wait for an installation to complete, and the call operator also doesn't enforce synchronous execution. If you need to wait for the installation to complete before proceeding you need something like the CMD-builtin start command or Start-Process. I would still recommend defining the parameters as an array, though.

$params = '/i', "$dirFiles\ABDS2017\Img\x64\RVT\RVT.msi",
          'INSTALLDIR="C:\Program Files\Autodesk"', 'ADSK_SETUP_EXE=1',
          '/qb!'
$p = Start-Process 'msiexec.exe' -ArgumentList $params -NoNewWindow -Wait -PassThru
$p.ExitCode
