VB6 - Windows 7 vs XP

We have a VB6 application running under Windows 7 using pdfCreator. When the application is compiled under XP all is fine but if the application is compiled under Windows 7 pdfCreator returns an error # 429.  I have installed version 0.9.9 and 1.3.2 with the same results.  Any ideas?

Are you using late binding

           ' late bind to whichever version PDFCreator is installed on this PC
            Set pdfJob = CreateObject(Class:="PDFCreator.clsPDFCreator")
