No "Lotus.Notessession" available

Hello,
i've tryed to write a small testapplication, that send a Email via
Lotus Notes by automation. I write this little app in Visual Foxpro
(the syntax is nearly VB).

----snip
loSession = CREATEOBJECT( "Lotus.NotesSession" )
loSession.Initialize( )
lcServer = loSession.GetEnvironmentString( "MailServer",.T.)
lcMaildbName = loSession.GetEnvironmentString( "MailFile",.T.)
loMaildb = loSession.getdatabase(lcServer, lcMaildbName )
loMaildoc = loMaildb.CreateDocument()
loMaildoc.ReplaceItemValue( "Logo", "Plain Text")
loMaildoc.ReplaceItemValue( "Form", "Memo" )
loMaildoc.ReplaceItemValue( "SendTo", "abc-at-abc.com" )
loMaildoc.ReplaceItemValue( "Subject", "Subject")
loMaildoc.SaveMessageOnSend = .T.
loStream = loSession.CreateStream()
loStream.WriteText( "Testtext" )
loBodyMime = loMaildoc.CreateMIMEEntity()
loBodyMime.SetContentFromText( loStream, "text/html;charset=iso-8859-1",
..F. )
loMaildoc.SEND(0)

On Notes 6.5 there is no problem everything is fine.
My problem is a Notes 6.0 intallation. There is no "Lotus.Notessession"
object.
I've scanned the whole registry. The only thing i have found is a
"Notes.Notessession" entry.
But with this entry the app is without any function. No Mail will send.

I dont have any ideas. Is there a was to use the Notes.Notessession-Object
or is there
a way out to use mapi to send a mail?

Any ideas welcom.

pls excuse me for my bad english.
