PowerShell:在不安装的情况下从 MSI 文件中获取 MSI 产品代码? [英] PowerShell: Get the MSI product code out of a MSI file without installing?

问题描述

是否有可能在不使用 PowerShell 安装的情况下从 MSI 文件中检索 MSI 产品代码?我想将 MSI 文件的产品代码与安装在机器上的 MSI 代码进行比较，以确定该文件是否曾经安装过.

Is there a possibility to retreive the MSI product code out of a MSI file without installing it with PowerShell? I want to compare the product code of a MSI file with the MSI codes installed on a maschine to find out if the file was installed in the past.

推荐答案

这里有一个脚本，根据 这篇文章:

Here is a script that reads the product code based on this article:

$path = "pathto.msi"

$comObjWI = New-Object -ComObject WindowsInstaller.Installer
$MSIDatabase = $comObjWI .GetType().InvokeMember("OpenDatabase","InvokeMethod",$Null,$comObjWI,@($Path,0))
$Query = "SELECT Value FROM Property WHERE Property = 'ProductCode'"
$View = $MSIDatabase.GetType().InvokeMember("OpenView","InvokeMethod",$null,$MSIDatabase,($Query))
$View.GetType().InvokeMember("Execute", "InvokeMethod", $null, $View, $null)
$Record = $View.GetType().InvokeMember("Fetch","InvokeMethod",$null,$View,$null)
$Value = $Record.GetType().InvokeMember("StringData","GetProperty",$null,$Record,1)

$Value 现在包含产品代码.
