vb.net 2010 not working with bullzip pdf

[QuickBooksDev]

We are converting an old VB6 program using bioPDF to vb.net 2010 with BullZip.

Downloded the lastest Bullzip and installed it.

Have tried to used the samples that we have seen but the classes intellisense do not seem to be generating the proper methods, etc.

Included references for
Bullzip 1.0 Type Library (Com 1.0.0.0)
and
Interop.Bullszip (com 3.2.0.0)

We have
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Drawing
Imports System.Linq
Imports System.Text
Imports System.IO
Imports Bullzip
Imports Bullzip.PdfWriter
Imports BullzipLib
Imports System.Runtime.InteropService

but pdfUtil is not found for the line
pdfUtil.PrintFile(fileName, PRINTERNAME)

I must be missing something.

Is there a good vb or c# example that works?

Thanks
