Install Problem on Windows XP Home - Password Issue

Hello,

I was installing the Windows version of PostgreSQL 8.0.3 (I am running
Windows XP Home) when I got to the screen that asks for a password, I left
if blank and went to the next screen. I decided to go back and change it but
now I get "Account error. Invalid username specified" and can't even install
the program. I searched Google and found this person with the same
problem...

The suggested solution is to delete the account and start over. The problem
is, I cannot find the account to delete it. Can anyone tell me where I would
look to find the account and delete it?

I've already gone to Control Panel/System clicked on the Advanced tab and
then clicked on the User Profiles section and postgres is not listed there.
Is there someone else I can look?
