PowerShell, Office 2007: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Interop.Wor‌​d")

Hi All,

I have problem to convert word document in to html (Office 2007)

Interop Assembly appear to work but powershell returns:

Unable to find type [Microsoft.Office.Interop.Word.WdSaveFormat]:  

I'using :

$saveFormat = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], “wdFormatFilteredHTML”);
