Convert office docs to html with VBScript in ASP.NET

Question

I am trying to convert office documents to html in an ASP.net application.

I have tried several methods including VBScript, SautinSoft UseOffice and VeryDoc doc2any

all the methods i suspect use VBScript to open office and perform a save as operation.

while this method works fine when i run it from command prompt, when it runs from ASP.NET it fails.

I tried running the application pool with an admin user account - that does not help.

any thoughts?

here is the VBscript:

Dim WordApp
Set WordApp = CreateObject("Word.Application")
If WordApp Is Nothing Then
	MsgBox "Couldn't start Word.", 48, "Application Start Error"
Else
	WordApp.Documents.Open WScript.Arguments.Item(0)
	WordApp.ActiveDocument.SaveAs WScript.Arguments.Item(1), 10
	WordApp.ActiveDocument.Close
End If
WordApp.Quit
Set WordApp = Nothing
