COM Object won't run from Win Service

[Relentless]

I'm trying to write a Windows Service that runs a COM object (WRQ Reflection Terminal Emulator) at regular intervals. This code works in a regular Win App. What am I doing wrong?

Private Sub RunReport()
        WriteFile("RunReport   " & Now)
        Dim Fab2SPN As Reflection1.Session
        Fab2SPN = CreateObject("Reflection1.Session")
        WriteFile("Fab2SPN   " & Now)
        With Fab2SPN
            .Visible = True
            .ConnectionType = "BEST-NETWORK"
            .ConnectionSettings = "Host SPNFAB1"
            .Connect()
            .WaitForHostTrigger()
        End With
End Sub

Protected Overrides Sub OnStart(ByVal args() As String)
     WriteFile ("Start   " & Now)
     RunReport()
End Sub

I referenced Reflection1 as usual. It won't even call the sub if the CreateObject is there.
The WriteFile is for debugging. Help
