Is this on a *nix box? Did you check to see if PostGreSQL created a user on the first install, and if that username is still existing on the box?

You have to delete user postgres, when installing postgres its creates a user account on windows, so delete this user and whole dir of previous installation.

I tried to find the user account on windows XP but it still displays my administrator name and the guest. there isn't' any other users account there. I receive the exact same messes as these individuals. is there somewhere else to look for the user account.

I don't use PostgreSQL on Windows, but it appears the Postgres creates a new user in a way that you don't see this account from Control Panel->Users, but you can find it if you look into your "%SystemDrive%\Documents and Settings\" directory.
(Typically C:\Documents and Settings)

C:\Documents and Settings> dir
Volume in drive C is System
Volume Serial Number is 50X2-9512

Directory of C:\Documents and Settings

04/15/2007 10:43 AM <DIR> .
04/15/2007 10:43 AM <DIR> ..
03/29/2007 09:44 PM <DIR> Administrator
03/20/2005 10:00 AM <DIR> All Users
04/05/2007 03:08 AM <DIR> Michael
04/15/2007 10:43 AM <DIR> postgres
0 File(s) 0 bytes
7 Dir(s) 45,362,515,968 bytes free
And if you opted for creating a detailed installation log when installing Postgres (seems like a good idea anyway) you will find the username there as well.

P.S. And thank you for searching and appending to the relevant thread, instead of just creating a new post!!

first delete the old postgres user from control panel - administrator tools - computer management - local user and groups - users - delete the psotgres user from this, then install the fresh postgres and check it, it may be working very well....., try and post your feedback
