How do I make Adobe Reader default pdf viewer?

When I click on a pdf link, Firefox gives an error that it can't find PDF Converter Professional 7.0. I've ensured Options|Applications links "Adobe Acrobat Document" to "Use Adobe Acrobat (in Forefox)", I've deleted the PDF Converter Professional plug-in -- but makes no difference.
