Getting MSI exit code when installing remotely using PowerShell

I use the following example to install some software on a remote computer

I would like to get the exit code back from the MSI so I can determine if successful or if not what the error was

I assumed $result would contain the information I need but I am obviously missing something

Ideas please?

$Result = Invoke-Command -computername MYREMOTEPC -ScriptBlock { Start-Process "msiexec" -ArgumentList "/i C:\tmp\MYSOFTWARE.msi /quiet /norestart" -Wait -Passthru }
Solution

  • Enclose the Start-Process -Passthru command in (...).ExitCode:

    $Result = Invoke-Command -computername MYREMOTEPC -ScriptBlock { 
 (
   Start-Process "msiexec" -ArgumentList "/i C:\tmp\MYSOFTWARE.msi /quiet /norestart" -Wait -PassThru
 ).ExitCode
}

    -PassThru instructs Start-Process to output a System.Diagnostics.Process instance representing the launched process, and given that -Wait is also used, its .ExitCode property can be accessed right away.
