>Where is the class defined? Perhaps you need to set procedure to ...exe, or to register the dll/exe.

Thanks for the reply Yuri.
I do set the path to where the prntpdf.exe file is. Here is the exact code:

SET PATH to oProp.ExePath
loPrntPdf = CREATEOBJECT("prntpdf.prntpdf")

The exe file contains one prg file with one class defined in it. Here are the fist line in the prg:

DEFINE CLASS PrntPdf AS Custom OLEPUBLIC

I will check into the set procedure.
