Postgresql installation problem??

HI 2 u
I’m trying to install PostgreSQL for windows XP, the version which I use is (postgresql-8-1.4-1). The problem is when I try to install it as a service I get an error message like this(Account error: Invalid username specified: logon failure: unknown user name or bad password).
If I tried to install it with as not a service it works, but then I can’t connect to database. An error message appears indicating that connection to database is failed.

Plz help & thanks in advance
