Should PB 2017 .NET assemblies be able to connect to ActiveX controls using ConnectToNewObject?

We are in the process of migrating PB 11.5 COM components to PB 2017 R2 .NET assemblies. One of these components integrates with an ActiveX control from Amyuni, which we use to open, manipulate and save PDF documents.

Our code In PB 11.5 COM:

oleobject ole_pdf
ole_pdf = create OLEObject
li_rc = ole_pdf.ConnectToNewObject("PDFCreactiveX.PDFCreactiveX.5.5")
 
try
// Attempt to open PDF
if aole_pdf.openex(as_filename, "") then
// Success
else
// Unable to open the PDF
end if
catch (oleruntimeerror err_pdfopenex)
lb_error = True
end try
 

In the .NET assembly target, li_rc is zero (no errors). But, the oleobject call to open the PDF fails. The CATCH is not executed, so there is no runtimeerror. Do we need some type of interop for communication with non-.NET libraries?

Thanks,
Don Olliver
