如何在PowerShell中运行Windows安装程序并获取成功/失败值？

# 检测安装程序是否已经运行
if (Get-Process -Name installer) {
    Write-Host "安装程序已经运行。"
} else {
    Write-Host "安装程序未运行。"
}

Start-Process -FilePath "path\to\setup.exe" -ArgumentList "/silent" -Wait

# 捕获安装程序的输出
$output = Start-Process -FilePath "path\to\setup.exe" -ArgumentList "/silent" -Wait -NoNewWindow | Out-String

# 输出成功/失败信息
if ($output -like "*成功*") {
    Write-Host "安装成功！"
} else {
    Write-Host "安装失败！"
}

# 设置安装成功/失败值
$success = $output -like "*成功*"

# 根据成功/失败值显示相应信息
if ($success) {
    Write-Host "安装成功！"
} else {
    Write-Host "安装失败，请检查安装过程中的问题。"
}
