My 2019 Desktop Quickbooks for Mac will not let me view and print paychecks or tax forms.  I just get a message that reads: Unable to find Acrobat reader; you should obtain this for best results in opening PDF files.  

I have already bought and updated the latest version of Adobe Acrobat.  I have cleared my history from Safari and selected Adobe as my default browser by control clicking a PDF file, all to no avail.  Now what?
