How do I find the MSI product version number using PowerShell?

Question

Our end deliverable has lot of MSI files.

I would ensure whether they has correct product name and product version.

I am using Orca and doing it manually.

This should have been an easy answer... To start with Windows Installer has a COM object you can use:

ProgID: WindowsInstaller.Installer

However when you create an object out of with PowerShell you don't get any of the properties or methods:

$object = New-Object -Com WindowsInstaller.Installer
$object | gm

...Nothing :-(

Apparently this is a problem with PowerShell and its type adapting system. See this blog post for a work around.

If you use VBScript you shouldn't have this problem.

EDIT:

Here's some VBScript that will get the version I found:

Const msiOpenDatabaseModeReadOnly = 0
Dim msi, db, view

Set msi = CreateObject("WindowsInstaller.Installer")
Set db = msi.OpenDataBase("C:\Users\andy\Desktop\Module.msi", msiOpenDatabaseModeReadOnly)
Set view = db.OpenView("SELECT `Value` FROM `Property` WHERE `Property` = 'ProductVersion'")
Call view.Execute()

GetVersion = view.Fetch().StringData(1)
Wscript.Echo GetVersion

You can call this from PowerShell:

$version = & cscript.exe /nologo GetVersion.vbs

Update! This type adaption problem was frustrating me and I wasn't happy with the VBS solution. After a bit of research I found a way to do this in PowerShell proper. I adapted code from his blog entry. Enjoy!

function Get-MsiDatabaseVersion {
    param (
        [string] $fn
    )

    try {
        $FullPath = (Resolve-Path $fn).Path
        $windowsInstaller = New-Object -com WindowsInstaller.Installer

        $database = $windowsInstaller.GetType().InvokeMember(
                "OpenDatabase", "InvokeMethod", $Null, 
                $windowsInstaller, @($FullPath, 0)
            )

        $q = "SELECT Value FROM Property WHERE Property = 'ProductVersion'"
        $View = $database.GetType().InvokeMember(
                "OpenView", "InvokeMethod", $Null, $database, ($q)
            )

        $View.GetType().InvokeMember("Execute", "InvokeMethod", $Null, $View, $Null)

        $record = $View.GetType().InvokeMember(
                "Fetch", "InvokeMethod", $Null, $View, $Null
            )

        $productVersion = $record.GetType().InvokeMember(
                "StringData", "GetProperty", $Null, $record, 1
            )

        $View.GetType().InvokeMember("Close", "InvokeMethod", $Null, $View, $Null)

        return $productVersion

    } catch {
        throw "Failed to get MSI file version the error was: {0}." -f $_
    }
}

Get-MsiDatabaseVersion "Installer.msi"
