Problems Converting word documents with the Adobe Printer and method ,printout (OutputFileName:=) in

Question

I would like to write a vb-procedure to convert a word document into pdf.
I'm developing in "Visual Basic 2005 express edition" and tried the following code:
code[
Private Sub PrintDocument(sDocName As String,sNewDocName As String)
'sDocname = "c:\tmp\test.doc"
'sNewDocName = "c:\test\test.pdf)
Dim m_wdApp As Word.Application = New Word.Application
Dim m_wdDatei As Word.Document
m_wdDatei = m_wdApp.Documents.Open(FileName:=sDocName)
m_wdDatei.PrintOut(Background:=False,OutputFileName:=sNewDocName, _ ActivePrinterMacGX:="Adobe PDF")
m_wdDatei.Close(False)
m_wdDatei = Nothing
m_wdApp.Quit()
m_wdApp = Nothing
End Sub
]End of code
After running the printout line I can see a little window popping up, which shows the progress in the converting and after a little time I can find the expected file in the targetdirectory.
The problem is that I can't open this file, I just get the message that the file is corrupt or not of the pdf-format.
By scanning the web, I found several threads describing the same problem, but so far I found no solution. Maybe someone here can help me.

You were right.
I've changed the default printer to "adobe printer" and created a new file. I thought the problem solved, but instead, the error is the same. The new file starts like this:
