When I try to install PokerTracke4 I´m having the error "Unable to login to database (postgres). Reason: could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "???" and accepting TCP/IP connections on port 5432? ".
After this I tried to install PostSQL but every time the installer opens, I get the elephant image and then....nothing happens.
Also followed the steps on your forum "https://www.pokertracker.com/guides/PT4/databases/how-to-manually-install-or-reinstall-postgresql-93-windows" but the problem keeps the same.
