我正在尝试在远程计算机上运行以下命令来卸载以前版本的产品，然后再安装另一个版本。这是使用 MsiExec.exe 进行卸载。

每当我调用 Start-Process 时，该进程实际上会运行并且产品会在远程计算机上卸载，但我会抛出以下异常。如果该产品尚未安装且 Start-Process 行未运行，则远程命令可以正常工作而不会引发异常。（即它实际上搜索注册表，没有找到产品，并返回 -1 而不抛出异常） 问题仅在调用 Start-Process 时出现。

这是我的脚本代码...

$UninstallScriptBlock = {
    param ( [string]$InstallerProductName )

    $ErrorActionPreference = "Stop";

    $UninstallRegPath = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
    $ProductCode = Get-ChildItem -Path $UninstallRegPath | foreach { if ($_.GetValue("DisplayName") -eq $InstallerProductName) { [System.IO.Path]::GetFileName($_); } }
    if ([string]::IsNullOrEmpty($ProductCode))
    {
        $UninstallRegPath = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
        $ProductCode = Get-ChildItem -Path $UninstallRegPath | foreach { if ($_.GetValue("DisplayName") -eq $InstallerProductName) { [System.IO.Path]::GetFileName($_); } }
    }
    if ([string]::IsNullOrEmpty($ProductCode))
    {
        return -1;
    }

    $Process = Start-Process -Wait -Passthru -FilePath "MsiExec.exe" -ArgumentList "/X", $ProductCode, "/qn";
    return $Process.ExitCode;
}

[int]$UninstallReturnCode = Invoke-Command -ComputerName $Server -ScriptBlock $UninstallScriptBlock -ArgumentList $InstallerProductName -SessionOption (New-PSSessionOption -OperationTimeout 0);

和抛出的异常......

我能找到的最佳答案是我的卸载正在重置 IIS，这导致我的 Powershell Remoting 连接被切断。

这就是我作为解决方法所做的：

  1. 从 Start-Process 中删除 -Wait 并立即关闭 Powershell Remoting 会话。
  2. Powershell Remoting 会话关闭后，进入 Start-Sleep 等待卸载完成（猜测卸载需要多长时间加上一些填充）。
  3. 阅读卸载日志文件中的文本“删除成功或错误状态：XXXX”。其中 XXXX 是卸载过程的返回码。
