我无法在Windows 7上使用PowerShell将我的SID转换为友好名称

Question

  

$ RootPath =“K：\ FolderName”

     

$ Folders = dir $ RootPath -recurse |其中{$ _.psiscontainer -eq $ true}

     

foreach（$文件夹中的$ Folder）{$ ACLs = get-acl $ Folder.fullname |   ForEach-Object {$ _.Access} Foreach（$ ACL中的$ ACL）       {

    $objSID = New-Object System.Security.Principal.SecurityIdentifier($ACL.IdentityReference) 
    // the above line gives an error
    $objUser = $objSID.Translate( [System.Security.Principal.NTAccount]) 
    $objUser.Value

    $OutInfo = $Folder.Fullname + "," + $objUser.Value  + "," + $ACL.AccessControlType + "," + $ACL.IsInherited + "," +

     

$ ACL.InheritanceFlags +“，”+ $ ACL.PropagationFlags           Add-Content -Value $ OutInfo -Path $ OutFile}}

错误是

+     $objSID = New-Object <<<<  System.Security.Principal.SecurityIdentifier($
ACL.IdentityReference) 
    + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodInvoca
