I did a fresh installation after deleting every reference to postgres and pgAdmin in the registry and removing the relevant folders. It looks as if the installation fails when loading additional modules. I also think host should be localhost at this stage. Here is a portion of the log that shows a definite error: *********************************************************************************************************** Script output: Starting postgresql-8.3 Service postgresql-8.3 started successfully startserver.vbs ran to completion Script stderr: Loading additional SQL modules...
