使用ScriptBlock上的凭据导致COM错误连接到应用程序

好的,我有一个概念验证脚本,看起来像这样连接到iTunes:

$username = Read-Host "Please enter your userid for the local machine"
$password = Read-Host "Please enter a password to be encrypted" -AsSecureString
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,$password)

Invoke-Command -ScriptBlock { 
    $iTunes = New-Object -ComObject iTunes.application
    $itunes | gm
} -ComputerName localhost -Credential $cred

但是它返回以下错误:

Retrieving the COM class factory for component with CLSID {DC0C2640-1415-4644-875C-6F4D769839BA} failed due to the following error: 80080005.
    + CategoryInfo          : ResourceUnavailable: (:) [New-Object], COMException
    + FullyQualifiedErrorId : NoCOMClassIdentified,Microsoft.PowerShell.Commands.NewObjectCommand

如果它变得有趣,如果我从脚本块中删除-ComputerName localhost -Credential $cred,它可以正常工作:

有谁知道为什么脚本块上的凭据可能导致此问题?

原因是我正在研究一种运行某些iTunes任务的方法,当从LOCAL SYSTEM服务调用时,所以在某种程度上,我正在尝试将呼叫提升回登录用户。
