Hi everyone,

does someone know how to read and change the SummaryInformation in a MSI package with PowerShell?

I am having already trouble with opening the information but please see below my code:

Thanks

Stephan

 Clear-Host
$installer = New-Object -ComObject WindowsInstaller.Installer
    $WorkingDir = "C:\Users\Desktop\"
    $MSI_file2 = "Sync.ism"

$scriptpath = Split-Path -parent $MyInvocation.MyCommand.Definition

$msiOpenDatabaseModeReadOnly = 0
$msiOpenDatabaseModeTransact = 1
$msiViewModifyUpdate = 2
$msiViewModifyReplace = 4
$msiViewModifyDelete = 6
$msiTransformErrorNone = 0
$msiTransformValidationNone = 0

function Invoke-Method ($Object, $MethodName, $ArgumentList) {
 return $Object.GetType().InvokeMember($MethodName, 'Public, Instance, InvokeMethod', $null, $Object, $ArgumentList)
}

function Get-Property ($Object, $PropertyName, [object[]]$ArgumentList) {
 return $Object.GetType().InvokeMember($PropertyName, 'Public, Instance, GetProperty', $null, $Object, $ArgumentList)
}

if ($database2 -ne $null){
[Runtime.InteropServices.Marshal]::FinalReleaseComObject($database2)
}
if ($summary -ne $null){
[Runtime.InteropServices.Marshal]::FinalReleaseComObject($summary)
}

$database2 = $Installer.GetType().InvokeMember("OpenDatabase", "InvokeMethod", $Null, $Installer, @(($WorkingDir + $MSI_file2), 0))

$summary = $database2.GetType().InvokeMember("SummaryInformation", "GetProperty", $Null, $database2, $Null, 1)

#$database2.GetType().GetProperty
$summary.GetType().InvokeMember("Persist", "InvokeMethod", $Null, $summary, $null)
