Error in PDFCreator setuplog.txt Port and Print Monitor

I am trying to create a setup for SourceForge PDFCreator using Inno Setup and getting following error in Setuplog.txt:

InstallPrinter:

What might be the reason?

Look up that error on the Inno Setup newsgroup search, and that should help you I think.
