Hi,

I am writing a PowerShell script that will automate the installation of MSI files. I also want this script to be able to open up a browse files dialog box so that the user can specify which MSI files to install (the basic version of this will allow for manual editing of the script for pre-determined installs).

This is the script I have at the moment. It works when I press play within the PowerShell ISE, but from the desktop/command line it just freezes. I've included the errors from ISE as well.

Also, it would be ideal to make it so that if the MSI does not install it does not prompt with 'MSI installed successfully' and rather says 'MSI did not install' or something to that effect.

(please note I do not receive any error when I run the script in ISE and select a file, only when I do not select a file and cancel I get this error)

Script:

function Select-FileDialog { param([string]$Title,[string]$Directory,[string]$Filter="All Files (*.*)|*.*") [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null $objForm = New-Object System.Windows.Forms.OpenFileDialog $objForm.InitialDirectory = $Directory $objForm.Filter = $Filter $objForm.Title = $Title $Show = $objForm.ShowDialog() If ($Show -eq "OK") { Return $objForm.FileName } Else { Write-Error "Operation cancelled by user." } }

$file = Select-FileDialog -Title "Select a file" -Directory "c:\msi" -Filter "MSI|*.msi"

$product= [WMICLASS]"\\localhost\ROOT\CIMV2:win32_Product"

$product.Install("$file")

$a = new-object -comobject wscript.shell

$b = $a.popup("OK! MSI Install has successfully installed",0,"Sporting Index",1)

I'm sorry, I'm reading quick... So if your only problem when you run this from the command-line?

This would have to do with the default threading used by powershell.exe. Look at the properties of your PowerShell shortcut icon, and add "-sta" to the command-line used to launch powershell.exe then retry.

Hi,

Yes when I run it from the command line nothing happens. Adding -sta does work, however, is there anyway to avoid this or automate it in the script? The idea will be to roll this PS script out to many servers, and it would cause a delay if each server would have to have the properties of each icon changed! :)

Any ideas as to the error messaging as well so it knows whether or not, and prompt accordingly, if it has been installed?

Also, is it possible to install EVERY MSI in a folder, as opposed to just one specified or selected?

Many thanks :)

You will not be able to avoid using STA with your current approach. You may need to have your script simply start another powershell.exe process with the -sta set that runs your script.

I don't know about your second question... You could parse the MSI chosen, and simply use it's base dir for a simple search so that everything is loaded?
