PokerTracker

I got a new computer and am struggling to get PT4 to work on it. When I DL the program this is the error I get and what happens when I follow the prompts:

When you installed PokerTracker 4 did it ask if it could install PostgreSQL (the program where PokerTracker 4 stores your poker data) for you? If so at the end of the install did it say it installed sucessfully or not? Do you see PostgreSQL in your Applications folder? If PostgreSQL isn't installed then you can manually download and install PostgreSQL v16 - see this guide:
