I'm trying to install pgagent from stackbuilder for my psql installation. However as you can see the installation is not showing up and I can't manage to find why.
I've reinstalled stackbuilder, the environment variables and path are also set up for psql bin, port 5432 is correctly set up in the firewall... Has anyone run into this issue and could help me? Thanks in advance.

I had to re-install PostgreSQL database along with Stackbuilder. That fixed the issue with the listing of the local installation.
Now that it lists, checking the registry shows the following entries: for:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\Services\postgresql-x64-15
