This user must also own the server process.

The default text search configuration will be set to "english".

Please try following these directions carefully to fully uninstall: Total uninstall/reinstall of PT3 & Postgres.

Are you running as an Administrator in windows 2000?
I'm not sure that postgres 8.3 supports w2k - I've just done a quick web search and it seems like there are a few people having problems with this - you may need to install 8.2 - I'll try to get one of our postgres experts to take a look at this thread.

I do not know see PostgreSQL 8.3 would not support Win2000.

I see two main problems:

1. Your "postgres" username already exists therefore you must go Start->Run, 'cmd' and at the command prompt type "net user postgres /delete"

2. If this is a new installation, make sure that you delete your Program Files/PostgreSQL directory before installing. If this is a re-installation then do not delete the directory but simply uncheck "Initialize Database Cluster" during that step which will keep your previous database in tact.
