I’m using a 64-bit Windows 10 computer and when I installed PostgreSQL and tried to open pgAdmin this is the error I get. I’ve tried solutions mentioned in the stackoverflow, but it’s not working. What could be the issue? Let me know.
Hi…
Have you tried this one: link
Summary:
This happens when a PGAdmin instance is already running but cannot be reached. To resolve this issue, delete all the files in the following directory:
C:\Users\username\AppData\Roaming\pgAdmin
To verify user:
- open command prompt
- type whoami
- hit return
- username in path above should match what is returned in command prompt
Then run PGAdmin4 again.
Also… A suggested solution on StackExchange for the NW.js has crashed error was to downgrade to pgAdmin III (link) - so if nothing else works…
Disclaimer: Amateur/Beginner here… Do wait for the experts before you decide to try downgrading…
Good luck troubleshooting
