Error 429 ActiveX can't create object from VBScript but not from VBA

Using the VBScript code below on Win 7 (and 8) I get Error 429 at line 2 on CreateObject when I run it with cscript. The Textextractor dll registers OK using regsvr32 from an elevated command prompt, and does not show any missing components when examined with depends.exe

Dim converter 
Set converter = CreateObject("TextExtractor.TextExtractorObj")
converter.ExtractText cronshaw.docx, cronshaw.txt
set converter = Nothing

But using VBA called from MS Access 2007 on Win 7 (and  8) the code below ran OK:

Public Sub Test()
Dim converter As Object
Set converter = CreateObject("TextExtractor.TextExtractorObj")
converter.ExtractText CurrentProject.Path & "\Cronshaw.docx", CurrentProject.Path & "\Cronshaw.txt"
End Sub

Any ideas why the VBScript fails where the VBA runs?
