Yes, it definitly does.

First - the fact that it can't find the DLL message file shows that
PostgreSQL is not properly installed. I take it it wasn't installed
using the official installer?

The "unepxected EOF" message is normal for any client that exits without
explicitly closing the connection.

This is a not too uncommon error, meaning that something broke your
TCP/IP stack. We've seen this many times, and it's usually either
antivirus or personal firewall software. If you have any of those on the
machine, try uninstalling them and see if that helps (sometimes it's
enough to disable them for the pg processes, sometimes you need to
uninstall them completely).

If that doesn't help, search for LSPfix - it's a tool that can help you
fix it.
