I am having serious problems getting pgAdmin 4 to load. I'm running on Windows 10. Please see attached screenshot. I have naturally tried to troubleshoot this problem myself. I have followed instructions from a google search to change the .js content type to have the value text/javascript in the registry editor and then closed pgadmin and its servers in task manager. Annoyingly I still get the same error message.

I previously tried to install postgreSQL about 2 months ago and then deleted it. Could it be that I have somehow caused a problem. I uninstalled postgreSQL by right clicking on it and clicking uninstall.

What else coud I try to troubleshoot this problem? Thank you

  • Do yourself a favor and use psql. It works reliably and is much more powerful.

I installed pgAdmin 4 directly from an exe file and that seems to have worked. I don't understand why it wouldn't install properly as part of the postgresq package but problem solved. :)

Edit : The link to working pgAdmin 4 is https://www.pgadmin.org/download/pgadmin-4-windows/

    This worked for me as well. pgAdmin4 8.7 that shipped with PostgreSQL 13 (I know it's old, I had to match the version my school uses) wouldn't start for anything. I too tried the reg key, file permissions, reboots, validating PostgreSQL had started correctly and was listening. I uninstalled just the pgAdmin part of the PostgreSQL package, installed pgAdmin4 8.9, and now it works.
