Unable to install PT4

Hello 
I recently got a new MacBook and transfered my entire old computer to my new computer. However, when I now try to set up Pokertracker, I get the message in the attached picture.
I already reinstalled PostgreSQL but I get the same message.
How can I fix that?
Thanks and best to regards
